feat(opt-dist): new flag `--benchmark-cargo-config` This should be the last piece toward self-contained `opt-dist` (I believe). The flag propagates cargo configs to `rustc-perf --cargo-config`, which is particularly useful when the environment is air-gapped, and you want to use the default set of training crates vendored in the rustc-src tarball. It fixes the issue described in #125465 > * The current pinned rustc-perf uses `tempfile::Tempdir` as the working directory when collecting profiles from some of these packages. This "tmp" working directory usage make it impossible for Cargo to pick up the correct vendor sources setting in `.cargo/config.toml` bundled in the rustc-src tarball.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
