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.

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

default_level: Level

Default level for the lint.

See https://rustc-dev-guide.rust-lang.org/diagnostics.html#diagnostic-levels for guidelines on choosing a default level.

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: bool

feature_gate: Option<Symbol>

Some if this lint is feature gated, otherwise None.

crate_level_only: bool

Layout

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.
