Struct rustc_middle::lint::LintExpectation
source · [−]pub struct LintExpectation {
pub reason: Option<Symbol>,
pub emission_span: Span,
pub is_unfulfilled_lint_expectations: bool,
pub lint_tool: Option<Symbol>,
}
Expand description
This struct represents a lint expectation and holds all required information
to emit the unfulfilled_lint_expectations
lint if it is unfulfilled after
the LateLintPass
has completed.
Fields
reason: Option<Symbol>
The reason for this expectation that can optionally be added as part of the attribute. It will be displayed as part of the lint message.
emission_span: Span
The Span
of the attribute that this expectation originated from.
is_unfulfilled_lint_expectations: bool
Lint messages for the unfulfilled_lint_expectations
lint will be
adjusted to include an additional note. Therefore, we have to track if
the expectation is for the lint.
lint_tool: Option<Symbol>
This will hold the name of the tool that this lint belongs to. For
the lint clippy::some_lint
the tool would be clippy
, the same
goes for rustdoc
. This will be None
for rustc lints

something which is needed when forcing DepNode
s during red-green
evaluation. The query system will only call this method if
fingerprint_style()
is not FingerprintStyle::Opaque
.
It is always valid to return None
here, in which case incremental
compilation will treat the query as having changed instead of forcing it. Read moresourceimpl<T, R> InternIteratorElement<T, R> for T
