Expand description
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_externally_loaded: bool
true
if this lint is being loaded by another tool (e.g. Clippy).
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.
