Pull request overview

Modernizes the Rust workspace by upgrading to Rust 2024 edition, refreshing key dependencies, and updating developer tooling/CI workflows.

Changes:

• Bump all crates to Rust edition 2024, update workspace resolver, and refresh dependency versions.
• Apply small Rust-idiomatic cleanups (e.g., div_ceil, Display, iterator simplifications).
• Modernize GitHub Actions CI/coverage workflows and simplify just tasks.

vm/src/loader.rs:34

• Adding #[allow(dead_code)] on a public field makes it easy to miss genuinely-unused API/data and can mask regressions when the field is expected to be read. If the header is intentionally kept for future use, consider either making the field private with an accessor, or using it in code paths that need it, rather than suppressing the lint at the field level.

pub struct Program {
    #[allow(dead_code)]
    pub header: Header,
    pub ro_block: Vec<u8>,
    pub program_text: Vec<u8>,

.github/workflows/coverage.yml:22

• cargo install cargo-tarpaulin without pinning a version (and without --locked) makes CI non-deterministic and can break unexpectedly when tarpaulin publishes a new release or dependency resolution changes. Prefer pinning a specific tarpaulin version and using --locked, or using an install action that supports version pinning/caching.

      - name: Install cargo-tarpaulin
        run: cargo install cargo-tarpaulin

      - name: Run cargo-tarpaulin
        run: cargo tarpaulin --out xml

.github/workflows/ci.yml:4

• This PR deletes the only release.yml workflow and there is no replacement under .github/workflows/. If releases are still expected to be automated, this removal will stop tag-based validation/release jobs; consider keeping a release workflow (modernized to current actions) or documenting the new release process in-repo.

argot/src/argot/compiler/first_pass.rs:16

• Using #[allow(dead_code)] to silence unused-field warnings on exported structs can hide real issues over time. If name/return_type are not part of the intended API, consider making them private (or removing them); if they are intended to be used later, consider adding the usage or a short comment explaining why the fields are retained.

pub struct FunctionDecl {
    #[allow(dead_code)]
    pub name: String,
    pub arguments: Vec<Argument>,
    #[allow(dead_code)]
    pub return_type: String,
}

header.ro_block_size + ELIS_HEADER_LENGTH can overflow on 32-bit (and will panic in debug or wrap in release), which can bypass this length check and later cause slicing panics when parsing untrusted bytecode. Consider using checked_add (and failing with ReadOnlySectionTooLong) before comparing against data.len() and before computing the slice bounds.
