rust plugin doesn't check if the Cargo.toml file exists
Metadata
Current evaluation
Rust plugin downloads its toolchain before Cargo reports a missing manifest when the build directory is empty; historical source-subdir handling was fixed, but explicit preflight validation remains absent.
Suggested action: needs triage
Reason: The report gives an exact Cargo failure and requests a small preflight check, but no activity has occurred since 2017. Commit 2c957a311 fixed the related source-subdir behavior, while the current Rust plugin still invokes toolchain setup before its build-time manifest lookup; maintainers should confirm whether early validation is still desired.

close resolved | An empty build directory caused Rust source-subdir builds to download the toolchain before Cargo failed; PR #1296 later fixed source-subdir handling so Cargo.toml is found. | |

needs triage | Rust plugin downloads the Rust toolchain before validating that Cargo.toml exists, causing a confusing late failure. Open ~10 years with zero comments; plugin now lives in craft-parts and still lacks an early existence check. | |
