Expand description

Specification of a single lint.

A string identifier for the lint.

This identifies the lint in attributes and in command-line arguments. In those contexts it is always lowercase, but this field is compared in a way which is case-insensitive for ASCII characters. This allowsdeclare_lint!() invocations to follow the convention of upper-case statics without repeating the name.

The name is written with underscores, e.g., “unused_imports”. On the command line, underscores become dashes.

See https://rustc-dev-guide.rust-lang.org/diagnostics.html#lint-namingfor naming guidelines.

Description of the lint or the issue it detects.

e.g., “imports that are never used”

Starting at the given edition, default to the given lint level. If this is None, then usedefault_level.

true if this lint is reported even inside expansions of external macros.

true if this lint is being loaded by another tool (e.g. Clippy).

Some if this lint is feature gated, otherwise None.

true if this lint should not be filtered out under any circustamces (e.g. the unknown_attributes lint)

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
