pub struct LintExpectation {

    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

impl<Tcx, T> DepNodeParams<Tcx> for Twhere Tcx: DepContext, T: for<'a> HashStable<StableHashingContext<'a>> + Debug,

source§

default fn fingerprint_style() -> FingerprintStyle

source§

default fn to_fingerprint(&self, tcx: Tcx) -> Fingerprint

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous).
source§

default fn to_debug_str(&self, _: Tcx) -> String

source§

default fn recover(_: Tcx, _: &DepNode) -> Option<T>

This method tries to recover the query key from the given DepNode, 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.

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.
