Expand description
Information about the registered lints.
This is basically the subset of Context
that we can
build early in the compile pipeline.
Fields§
§lints: Vec<&'static Lint>
Registered lints.
pre_expansion_passes: Vec<Box<dyn Fn() -> Box<dyn EarlyLintPass + 'static> + DynSend + DynSync>>
Constructor functions for each variety of lint pass.
These should only be called once, but since we want to avoid locks or interior mutability, we don’t enforce this (and lints should, in theory, be compatible with being constructed more than once, though not necessarily in a sane manner. This is safe though.)
early_passes: Vec<Box<dyn Fn() -> Box<dyn EarlyLintPass + 'static> + DynSend + DynSync>>
§late_passes: Vec<Box<dyn for<'tcx> Fn(TyCtxt<'tcx>) -> Box<dyn LateLintPass<'tcx> + 'tcx> + DynSend + DynSync>>
§late_module_passes: Vec<Box<dyn for<'tcx> Fn(TyCtxt<'tcx>) -> Box<dyn LateLintPass<'tcx> + 'tcx> + DynSend + DynSync>>
This is unique in that we construct them per-module, so not once.
by_name: FxHashMap<String, TargetLint>
Lints indexed by name.
lint_groups: FxHashMap<&'static str, LintGroup>
Map of registered lint groups to what lints they expand to.

)
pub fn register_pre_expansion_pass( &mut self, pass: impl Fn() -> Box<dyn EarlyLintPass + 'static> + 'static + DynSend + DynSync )
This lint pass is softly deprecated. It misses expanded code and has caused a few errors in the past. Currently, it is only used in Clippy. New implementations should avoid using this interface, as it might be removed in the future.

pub fn register_group( &mut self, from_plugin: bool, name: &'static str, deprecated_name: Option<&'static str>, to: Vec<LintId> )
sourcepub fn register_ignored(&mut self, name: &str)
pub fn register_ignored(&mut self, name: &str)
This lint should give no warning and have no effect.
This is used by rustc to avoid warning about old rustdoc lints before rustdoc registers them as tool lints.
sourcepub fn register_renamed(&mut self, old_name: &str, new_name: &str)
pub fn register_renamed(&mut self, old_name: &str, new_name: &str)
This lint has been renamed; warn about using the new name and apply the lint.
pub fn register_removed(&mut self, name: &str, reason: &str)
pub fn find_lints(&self, lint_name: &str) -> Result<Vec<LintId>, FindLintError>
sourcepub fn is_lint_group(&self, lint_name: Symbol) -> bool
pub fn is_lint_group(&self, lint_name: Symbol) -> bool
True if this symbol represents a lint group name.
sourcepub fn check_lint_name(
&self,
lint_name: &str,
tool_name: Option<Symbol>,
registered_tools: &RegisteredTools
) -> CheckLintNameResult<'_>
pub fn check_lint_name( &self, lint_name: &str, tool_name: Option<Symbol>, registered_tools: &RegisteredTools ) -> CheckLintNameResult<'_>
Checks the name of a lint for its existence, and whether it was renamed or removed. Generates a DiagnosticBuilder containing a warning for renamed and removed lints. This is over both lint names from attributes and those passed on the command line. Since it emits non-fatal warnings and there are two lint passes that inspect attributes, this is only run from the late pass to avoid printing duplicate warnings.

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.
