Type Alias rustc_middle::query::queries::shallow_lint_levels_on::ProvidedValue

pub type ProvidedValue<'tcx> = ShallowLintLevelMap;

This type alias specifies the type returned from query providers and the type used for decoding. For regular queries this is the declared returned type V, but arena_cache will use <V as Deref>::Target instead.

Implementations

impl ShallowLintLevelMap

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.

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.

Trait Implementations

impl Debug for ShallowLintLevelMap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ShallowLintLevelMap

fn default() -> ShallowLintLevelMap

Returns the “default value” for a type.

impl<'__ctx> HashStable<StableHashingContext<'__ctx>> for ShallowLintLevelMap

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher )

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.
