Caution The consumer version of Gemini Code Assist on GitHub has been sunset. All code review activity has officially ceased. |
The CI fuzz job was failing because the standard library source code (`rust-src`) was missing, which is required when building with `-Z build-std`. This commit adds the `rust-src` component to the `rust-toolchain` setup in the `cifuzz.yml` workflow.
The CodeQL CI check fails because "CodeQL analyses from advanced configurations cannot be processed when the default setup is enabled". This means Default Setup is enabled on the repository for Code Scanning, so we need to remove this workflow file to prevent conflicts.

Resolves merge conflicts on PR to fix the CodeQL workflow issue and the HugeBuffer Drop panic issue.
The clippy warning `clippy::needless_late_init` triggered in `src/api.rs`. This commit fixes the warning by moving the declaration `stack_limit` and removing the assignments from the branches, satisfying clippy.

HugeBuffer'sDropimplementation whereLayout::from_size_align(...).unwrap()was used.Dropimplementation can cause a program abort, leading to a denial-of-service vulnerability, particularly if unwinding is already occurring.🛡️ Solution: Replaced
unwrap()withLayout::from_size_align_unchecked(...). This is safe because the layout parameters were verified as valid during the initial allocation of the buffer.PR created automatically by Jules for task 12717776091592880656 started by @panayang
