Struct rustc_middle::lint::ShallowLintLevelMap

source · 
pub struct ShallowLintLevelMap {
    pub specs: SortedMap<ItemLocalId, FxIndexMap<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.

Implementations§

source§

impl ShallowLintLevelMap

source

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.

source

pub fn lint_level_id_at_node( &self, tcx: TyCtxt<'_>, lint: LintId, cur: HirId ) -> (Level, LintLevelSource)

Fetch and return the user-visible lint level for the given lint at the given HirId.

impl<Tcx, T> DepNodeParams<Tcx> for T
where 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.
