Fix some issues around `rustc_public` cc rust-lang/rust#148266 . follow-up of rust-lang/rust#148341 . This fixes the issues that can be reproduced by `x test compiler/rustc_public`: ``` error: function `run` is never used --> compiler/rustc_public/src/compiler_interface.rs:838:15 | 838 | pub(crate) fn run<'tcx, F, T>(interface: &CompilerInterface<'tcx>, f: F) -> Result<T, Error> | ^^^ | = note: `-D dead-code` implied by `-D warnings` = help: to override `-D warnings` add `#[allow(dead_code)]` error: unreachable `pub` item --> compiler/rustc_public/src/unstable/mod.rs:25:1 | 25 | pub trait InternalCx<'tcx>: Copy + Clone { | ---^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | | | help: consider restricting its visibility: `pub(crate)` | = help: or consider exporting it for use by other crates = note: `-D unreachable-pub` implied by `-D warnings` = help: to override `-D warnings` add `#[allow(unreachable_pub)]` error: unreachable `pub` item --> compiler/rustc_public/src/unstable/mod.rs:62:1 | 62 | pub trait Stable<'tcx>: PointeeSized { | ---^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | | | help: consider restricting its visibility: `pub(crate)` | = help: or consider exporting it for use by other crates error: unreachable `pub` item --> compiler/rustc_public/src/unstable/mod.rs:81:1 | 81 | pub trait RustcInternal { | ---^^^^^^^^^^^^^^^^^^^^ | | | help: consider restricting its visibility: `pub(crate)` | = help: or consider exporting it for use by other crates error: could not compile `rustc_public` (lib) due to 4 previous errors ```
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).
