rustc_lint/
lib.rs

1//! Lints, aka compiler warnings.
2//!
3//! A 'lint' check is a kind of miscellaneous constraint that a user _might_
4//! want to enforce, but might reasonably want to permit as well, on a
5//! module-by-module basis. They contrast with static constraints enforced by
6//! other phases of the compiler, which are generally required to hold in order
7//! to compile the program at all.
8//!
9//! Most lints can be written as [`LintPass`] instances. These run after
10//! all other analyses. The `LintPass`es built into rustc are defined
11//! within [rustc_session::lint::builtin],
12//! which has further comments on how to add such a lint.
13//! rustc can also load external lint plugins, as is done for Clippy.
14//!
15//! See <https://rustc-dev-guide.rust-lang.org/diagnostics.html> for an
16//! overview of how lints are implemented.
17//!
18//! ## Note
19//!
20//! This API is completely unstable and subject to change.
