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: SpanThe Span of the attribute that this expectation originated from.
is_unfulfilled_lint_expectations: boolLint 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 DepNodes 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 moresource§impl<T, R> InternIteratorElement<T, R> for T

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.
