Struct rustc_middle::lint::ShallowLintLevelMap
source · pub struct ShallowLintLevelMap {
pub specs: FxHashMap<LintId, LevelAndSource>,
}Expand description
Return type for the shallow_lint_levels_on query.
This map represents the set of allowed lints and allowance levels given by the attributes for a single HirId.
Fields
specs: FxHashMap<LintId, LevelAndSource>Implementations
sourceimpl ShallowLintLevelMap
impl ShallowLintLevelMap
sourcefn probe_for_lint_level(
&self,
tcx: TyCtxt<'_>,
id: LintId,
start: HirId
) -> (Option<Level>, LintLevelSource)
fn probe_for_lint_level(
&self,
tcx: TyCtxt<'_>,
id: LintId,
start: HirId
) -> (Option<Level>, LintLevelSource)
Perform a deep probe in the HIR tree looking for the actual level for the lint.
This lint level is not usable for diagnostics, it needs to be corrected by
reveal_actual_level beforehand.
sourcepub fn lint_level_id_at_node(
&self,
tcx: TyCtxt<'_>,
lint: LintId,
id: HirId
) -> (Level, LintLevelSource)
pub fn lint_level_id_at_node(
&self,
tcx: TyCtxt<'_>,
lint: LintId,
id: HirId
) -> (Level, LintLevelSource)
Fetch and return the user-visible lint level for the given lint at the given HirId.

default fn fingerprint_style() -> FingerprintStyle
sourcedefault fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint
default fn to_fingerprint(&self, tcx: Ctxt) -> 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). Read more
default fn to_debug_str(&self, Ctxt) -> String
sourcedefault fn recover(Ctxt, &DepNode<<Ctxt as DepContext>::DepKind>) -> Option<T>
default fn recover(Ctxt, &DepNode<<Ctxt as DepContext>::DepKind>) -> 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. Read moresourceimpl<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.
