Add unstable `--print=supported-crate-types` option MCP: https://github.com/rust-lang/compiler-team/issues/836 Tracking issue: https://github.com/rust-lang/rust/issues/138640 ### Test coverage Two tests: 1. `tests/ui/print-request/stability.rs` to check that `--print=supported-crate-types` is `-Zunstable-options`-gated 2. `tests/ui/print-request/supported-crate-types.rs` is added as a basic smoke test. Observe that the compiler stdout corresponds to the below *Example output* section (e.g. `proc-macro` is unsupported on `wasm32-unknown-unknown` currently). ### Example output <details> <summary>For `x86_64-unknown-linux-gnu`</summary> Notice the presence of `{c,}dylib` and `proc-macro`: ``` bin cdylib dylib lib proc-macro rlib staticlib ``` </details> <details> <summary>For `wasm32-unknown-unknown`</summary> Notice the absence of `dylib` and `proc-macro`: ``` bin cdylib lib rlib staticlib ``` </details> <details> <summary>For `x86_64-unknown-linux-musl`</summary> Notice the absence of `{c,}dylib` but presence of `proc-macro`: ``` bin lib proc-macro rlib staticlib ``` </details> ### Documentation I added an entry in the unstable book's print request section to document this `supported-crate-types` print request. ### Unresolved questions - [ ] (Name bikeshedding) is `supported-crate-types` a good name for the print request? I'm inclined to say it's good enough for an unstable print request, but may be worth revisiting at stabilization time. ### Stability This print request being added is *unstable* in this PR. A separate stabilization PR following the usual compiler flag stabilization procedure should be filed for stabilization after some baking time. ### Review remarks Best reviewed commit-by-commit. r? compiler |

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 integrated 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).
