Specification of a single lint.

Fields

name: &'static str

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 allows declare_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.

default_level: Level

Default level for the lint.

desc: &'static str

Description of the lint or the issue it detects.

e.g., "imports that are never used"

edition_lint_opts: Option<(Edition, Level)>

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

report_in_external_macro: bool

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

future_incompatible: Option<FutureIncompatibleInfo>is_plugin: boolfeature_gate: Option<Symbol>

Some if this lint is feature gated, otherwise None.

crate_level_only: bool
