)
fn opt_span_lint<S: Into<MultiSpan>>( &self, lint: &'static Lint, span: Option<S>, decorate: impl for<'a, 'b> FnOnce(&'b mut Diag<'a, ()>), )

source§fn get_lint_level(&self, lint: &'static Lint) -> Level
fn get_lint_level(&self, lint: &'static Lint) -> Level
This returns the lint level for the given lint at the current location.
source§fn emit_span_lint<S: Into<MultiSpan>>(
&self,
lint: &'static Lint,
span: S,
decorator: impl for<'a> LintDiagnostic<'a, ()>,
)
fn emit_span_lint<S: Into<MultiSpan>>( &self, lint: &'static Lint, span: S, decorator: impl for<'a> LintDiagnostic<'a, ()>, )
Emit a lint at
span
from a lint struct (some type that implements LintDiagnostic
,
typically generated by #[derive(LintDiagnostic)]
).source§fn span_lint<S: Into<MultiSpan>>(
&self,
lint: &'static Lint,

)
fn span_lint<S: Into<MultiSpan>>( &self, lint: &'static Lint, span: S, decorate: impl for<'a, 'b> FnOnce(&'b mut Diag<'a, ()>), )
Emit a lint at the appropriate level, with an associated span.
source§fn emit_lint(
&self,
lint: &'static Lint,
decorator: impl for<'a> LintDiagnostic<'a, ()>,
)
fn emit_lint( &self, lint: &'static Lint, decorator: impl for<'a> LintDiagnostic<'a, ()>, )
Emit a lint from a lint struct (some type that implements
LintDiagnostic
, typically
generated by #[derive(LintDiagnostic)]
).source§fn lint(
&self,
lint: &'static Lint,
decorate: impl for<'a, 'b> FnOnce(&'b mut Diag<'a, ()>),
)
fn lint( &self, lint: &'static Lint, decorate: impl for<'a, 'b> FnOnce(&'b mut Diag<'a, ()>), )
Emit a lint at the appropriate level, with no associated span.
source§fn fulfill_expectation(&self, expectation: LintExpectationId)
fn fulfill_expectation(&self, expectation: LintExpectationId)
This function can be used to manually fulfill an expectation. This can
be used for lints which contain several spans, and should be suppressed,
if either location was marked with an expectation. Read more

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
