rustc_lint/

lib.rs

//! Lints, aka compiler warnings.
//!
//! A 'lint' check is a kind of miscellaneous constraint that a user _might_
//! want to enforce, but might reasonably want to permit as well, on a
//! module-by-module basis. They contrast with static constraints enforced by
//! other phases of the compiler, which are generally required to hold in order
//! to compile the program at all.
//!
//! Most lints can be written as [`LintPass`] instances. These run after
//! all other analyses. The `LintPass`es built into rustc are defined
//! within [rustc_session::lint::builtin],
//! which has further comments on how to add such a lint.
//! rustc can also load external lint plugins, as is done for Clippy.
//!
//! See <https://rustc-dev-guide.rust-lang.org/diagnostics.html> for an
//! overview of how lints are implemented.
//!
//! ## Note
//!
//! This API is completely unstable and subject to change.
