One end-to-end test workflow file is now syntactically invalid and will fail to start, so that automation stops running until the misplaced permission line is removed. Two smaller issues remain: the Scorecard workflow grants write and identity-token scopes more broadly than its single job needs, and the Rust toolchain is declared inconsistently between the tool configuration files and the CI pipeline, which can produce different build behaviour locally versus in CI.

18-18: LGTM!

.github/workflows/scorecard.yml (2)

15-15: 🎯 Functional Correctness

.github/workflows/scorecard.yml:20-23 omits actions, so the job-level permissions do not inherit workflow-level actions: read. However, the pinned reusable workflow cannot be resolved: GitHub returns 422 for commit 5b1d00229e5e8c0c0fbfedc7e80f37ea50f49236, and its raw file URL returns 404. Whether the reusable workflow requires actions: read is therefore undecidable.


24-24: 🔒 Security & Privacy | 🛡️ Analyzed with Security Review

Resolve the reusable workflow references before defining secret mappings.

The pinned commit does not resolve in hyperpolymath/standards, so the callee secret inputs cannot be determined. Update the references or provide the callee definitions, then replace secrets: inherit with mappings for only the declared secrets.

29-29: 🔒 Security & Privacy | 🛡️ Analyzed with Security Review

Correct the invalid reusable-workflow pins first.

The SHA 5b1d00229e5e8c0c0fbfedc7e80f37ea50f49236 does not exist in hyperpolymath/standards, so neither workflow can load at this reference. After selecting valid pins, replace secrets: inherit with mappings for only the secrets each workflow requires.

14-14: 🎯 Functional Correctness

The openssf-compliance job only checks repository files and runs actions/checkout; it does not call the Actions API. The job-level contents: read permission therefore does not cause the claimed failure.

official mise Rust tool version syntax nightly channel documentation

💡 Result:

<search_synthesis>
In mise, you can manage Rust toolchains, including the nightly channel, using standard mise commands and configuration files [1][2]. ### Using the Nightly Channel To configure your project to use the rolling nightly channel, you can use the following command: mise use -g rust@nightly [1] This entry in your mise.toml ensures that mise resolves the nightly channel to a concrete nightly-YYYY-MM-DD toolchain [1][3]. Mise handles the locking mechanism to ensure reproducible installs while allowing you to update the nightly version when desired [1][3]. ### Pinning a Specific Nightly Version To pin a specific nightly build for exact reproducibility, you can configure it by date: mise use -g rust@nightly-2026-08-13 [1] ### Managing Multiple Versions You can define multiple Rust toolchains in your mise.toml by providing an array of tool objects [4]. This is useful if you need to use different toolchains for different components or tasks: [tools] rust = [ { version = "nightly", components = ["rustfmt"] }, { version = "1.83.0", components = ["clippy"] } ] [2][4] ### Key Configuration Options The rust backend supports several options within your mise.toml to customize the installation: - version: The channel (e.g., "nightly", "stable") or specific version (e.g., "1.83.0") [1][2]. - components: A list of components to install (e.g., ["rust-src", "llvm-tools"]) [1][2]. - profile: Sets the rustup profile (e.g., "minimal", "default") [2]. - targets: Specifies platforms for cross-compilation [2]. For cargo-installed tools that require a specific toolchain without changing your global Rust environment, you can use the install_env option to scope the toolchain: [tools] "cargo:some-tool" = { version = "latest", install_env = { RUSTUP_TOOLCHAIN = "nightly" } } [5]

<title>Rust | mise-en-place</title> https://mise.en.dev/lang/rust.html Rust | mise-en-place # Rust ​ Rust/cargo can be installed which uses rustup under the hood. mise will install rustup if it is not already installed and install the requested toolchain, components, and targets. By default, mise respects the `RUSTUP_HOME` and `CARGO_HOME` environment variables for the home directories and falls back to their standard location (`~/.rustup` and `~/.cargo`) if they are not set. You can change this by setting the `MISE_RUSTUP_HOME` and `MISE_CARGO_HOME` environment variables if you&`#39`;d like to isolate mise&`#39`;s rustup/cargo from your other rustup/cargo installations. These variables can also be set in mise configuration. They are applied to Rust operations in the same mise invocation: ``` [env] MISE_RUSTUP_HOME = "{{env.HOME}}/.local/share/rustup" MISE_CARGO_HOME = "{{env.HOME}}/.local/share/cargo" ``` Explicit `RUSTUP_HOME` and `CARGO_HOME` values in `[env]` take precedence over their corresponding `MISE_` variables. When the standard Rust homes have not been initialized and no home override is configured, mise can also reuse a package-manager installation of rustup. The original `PATH` must contain a directory with the `rustup`, `cargo`, and `rustc` proxies, as provided by package managers such as Homebrew, APT, and pacman. An explicit Rust or Cargo home continues to use mise&`#39`;s managed rustup initialization instead of an external proxy directory. Unlike most tools, these won&`#39`;t exist inside of `~/.local/share/mise/installs` because they are managed by rustup. mise keeps a symlink there for install tracking, sets the `RUSTUP_TOOLCHAIN` environment variable to the requested version, and asks rustup to install any configured components or targets when you run `mise install`. ## Usage ​ Use the latest stable version of rust: ``` mise use -g rust cargo build ``` Use the latest beta version of rust: ``` mise use -g rust@beta cargo build ``` Use the rolling nightly channel: ``` mise use -g rust@nightly cargo build ``` The configuration remains `nightly`, while mise resolves the current Rust channel manifest to a concrete `nightly-YYYY-MM-DD` toolchain for installation and lockfiles. This keeps the configured channel rolling while making locked installs reproducible. Run `mise upgrade rust` or `mise lock --bump` to advance the locked nightly. To keep a specific nightly instead, configure its date explicitly: ``` mise use -g rust@nightly-2026-08-13 ``` An explicitly dated nightly is an exact pin. Commands using `--bump`, such as `mise upgrade --bump rust`, can replace that pin with the current nightly. Use a specific version of rust: ``` mise use -g [email protected] cargo build ``` ## Tool Options ​ The following tool-options are available for the `rust` backend—these go in `[tools]` in `mise.toml`. ### `install_env` ​ Set environment variables for rustup install commands: ``` [tools] rust = { version = "latest", install_env = { RUSTUP_DIST_SERVER = "https://static.rust-lang.org" } } ``` ### `components` ​ The `components` option allows you to specify which components to install. Multiple components can be specified as an array or by separating them with a comma. The set of available components may vary with different releases and toolchains. Please consult the Rust documentation for the most up-to-date list of components. ``` [tools] "rust" = { version = "1.83.0", components = ["rust-src", "llvm-tools"] } ``` If the Rust toolchain is already installed, `mise install` will still add any missing configured components. ### `profile` ​ The `profile` option allows you to specify the type of release to install. The following values are supported: - `minimal`: Includes as few components as possible to get a working compiler (`rustc`, `rust-std`, and `cargo`) - `default`: Includes all of the components in the minimal profile, and adds `rust-docs`, `rustfmt`, and `clippy` - `complete`: Includes all the components…[truncated] <title>Result 2</title> https://mise.jdx.dev/lang/rust.html Skip to content Menu Return to top # Rust ​ Rust/cargo can be installed which uses rustup under the hood. mise will install rustup if it is not already installed and install the requested toolchain, components, and targets.

This should never be used, as it includes every component ever included in the metadata and thus will almost always fail. If not set, it defaults to the profile configured in `rustup`. You can check your current default by running `rustup show profile`. toml ``` [tools] "rust" = { version = "1.83.0", profile = "minimal" } ``` ### `targets` ​ The `targets` option allows you to specify a list of platforms to install for cross-compilation.

The only way I can get mise to install the newest is by running`mise install -f rust@nightly`.`rustup` itself has similar problem except that`rustup update` does update to the latest nightly. The lockfile doesn&`#39`;t have any information on the exact version of rust when using nightly. [tools.rust] version = "nightly" backend = "core:rust" When installing with`@nightly` the version should be locked to the latest nightly, e.g.`nightly-2025-03-28`. The`mise outdated`(and other subcommands) also need support for the`nightly-$DATE` versions as currently if your rust version is e.g.`nightly-2025-03-28` mise shows it always to be up-to-date. Would be nice if it also used data from the rustup-components-history project to only suggest versions which have the components you are requiring. `mise doctor` output version: 2025.3.10 macos-arm64 (2025-03-26) activated: yes shims_on_path: no build_info: Target: aarch64-apple-darwin Features: DEFAULT, NATIVE_TLS, OPENSSL, SELF_UPDATE Built: Wed, 26 Mar 2025 21:41:05 +0000 Rust Version: rustc 1.85.1 (4eb161250 2025-03-15) Profile: release shell: /opt/homebrew/bin/bash GNU bash, versio 5.2.37(1)-release (aarch64-apple-darwin24.0.0) Copyright (C) 2022 Free Software Foundation, Inc.

For the moment rust is managed outside of mise and I do: `[tasks.check] description = "Lint the code" run = [ "cargo machete", "cargo +nightly fmt --all -- --check || ( cargo +nightly fmt --all && exit 1 )", "cargo clippy --locked --all-targets -- -D warnings" ] ` And my CI setup looks like: ` - uses: dtolnay/rust-toolchain@e97e2d8 # master with: toolchain: nightly components: rustfmt - uses: dtolnay/rust-toolchain@e97e2d8 # master with: toolchain: "1.89" components: clippy - uses: jdx/mise-action@5ac50f7 # v3.2.0 with: experimental: true # needed for Go dependencies ` I&`#39`;d love to use mise and get rid of the rust-toolchain actions. I&`#39`;ve tried doing: `rust = {version = "1.89"} ` But with no success as then I don&`#39`;t have the nightly toolchain installed. I&`#39`;m running out of ideas so would love folks suggestions/opinions :) | | --- | 1 Answered by roele Sep 12, 2025 Never tried this myself but`mise.toml` supports multiple versions. So in context of CI you could actually define multiple rust versions in your config. ``` mise_toml: | [tools] rust = [ { version = "nightly", components = "rustfmt" }, { version = "1.89.0", components = "clippy" } ] ``` View full answer ## Replies: 1 comment · 1 reply edited ### roele Sep 12, 2025 | Never tried this myself but`mise.toml` supports multiple versions.

I had to put an extra: `[env] # needed because the 2 rust versions installed by mise may be switched around RUSTUP_TOOLCHAIN="1.89.0" ` Just because nightly gets installed after so the default toolchain was wrong.

Is it possible to use the nightly toolchain for only these tools? If not, could it be added as a setting? 1 Answered by risu729 May 27, 2026 Yes. For a single`cargo:` tool, use the documented per-tool`install_env` option to set the rustup toolchain just for that install command: ``` [tools] "cargo:some-tool" = { version = "latest", install_env = { RUSTUP_TOOLCHAIN = "nightly" } } ``` The cargo backend applies`install_env` to`cargo install`/`cargo-binstall`, and mise&`#39`;s Rust backend uses rustup toolchains via`RUSTUP_TOOLCHAIN`, so this scopes nightly to that cargo tool install instead of changing the stable Rust toolchain used elsewhere. Make sure the nightly toolchain is installed or otherwise available to rustup first. This comment was generated by an AI coding assistant. View full answer ## 1 comment ### risu729 May 27, 2026 Yes.

Pin the Rust toolchain in the canonical mise configuration.

mise.toml also declares rust = "latest", while .mise.toml declares rust = "nightly". Neither selector is fixed, and CI uses rust:latest. Pin one Rust toolchain and use it consistently in mise and CI.

In @.mise.toml at line 11, Pin the Rust toolchain consistently across the
canonical mise configuration and CI: replace the floating selectors in the mise
declarations, including the rust setting near this .mise.toml entry and the
`rust` setting in `mise.toml`, and update the CI `rust` version to the same
fixed toolchain. Preserve the existing configuration structure while ensuring
all consumers use one explicit version.
