Rust

Cargo and toolchain failures in CI - fixed.

Debug Rust CI failures: cargo build and dependency errors, lockfile issues, linker problems, toolchain mismatches, and out-of-memory compilation. Reliable fixes for cargo pipelines.

Cargo & dependencies

Resolution, registry, and lockfile errors.

"required for offline mode"Fix cargo "error: failed to download ... but --offline was specified" in CI - a crate isn’t in the local "could not find Cargo.toml"Fix cargo "error: could not find Cargo.toml in <dir> or any parent directory" in CI - the job runs in the "failed to authenticate (git)"Fix cargo "failed to authenticate when downloading repository" for a private git dependency in CI -- missing "failed to select a version"Fix cargo "error: failed to select a version for the requirement" in CI - incompatible version requirements "lock file needs to be updated"Fix cargo "the lock file needs to be updated but --locked was passed" in CI - Cargo.toml changed without "no matching package named"Fix cargo "error: no matching package named X found" in CI - a typo, a crate that lives in a workspace/path, "clippy: -D warnings"Fix cargo clippy failures in CI when run with `-D warnings` -- lints that are warnings locally become hard cargo-deny check failedFix cargo-deny / cargo-audit failures in CI - a RUSTSEC advisory, a banned/duplicate crate, or a disallowed

Build & link

Compiler, linker, and memory failures.

cargo nextest failureFix cargo-nextest failures in CI - a test failed, leaked, timed out, or was aborted by the per-test slow/leak "E0432: unresolved import"Fix Rust "error[E0432]: unresolved import" in CI - a missing crate, a wrong path, or a feature-gated item "E0507: cannot move out"Fix Rust "error[E0507]: cannot move out of X which is behind a shared reference" in CI -- you tried to move a "out of memory during codegen"Fix rust "LLVM ERROR: out of memory" during LTO codegen in CI -- fat link-time optimization holds the whole "rustc interrupted by SIGKILL"Fix rust "error: rustc interrupted by signal 9 (SIGKILL)" in CI -- the OOM killer terminated rustc because "sccache: failed to start"Fix sccache failures in CI - "failed to start server", "connection to server failed", or a misconfigured

Toolchain

rustup, targets, and edition mismatches.

"E0463: can't find crate for std"Fix Rust "error[E0463]: can't find crate for `std`" / "std not available" in CI - the target’s std isn’t "rustup: command not found"Fix "rustup: command not found" / "cargo: command not found" in CI - Rust isn’t installed or ~/.cargo/bin "the 'cargo' binary ... does not exist"Fix rustup "error: the cargo binary for the active toolchain does not exist" in CI -- a corrupt or partial
