Emit a lint from a lint struct (some type that implements
DecorateLint
, typically
generated by #[derive(LintDiagnostic)]

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

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.
