Implementations

impl<'db> FeatureKind<'db>

pub fn from_ast( db: &'db dyn Database, diagnostics: &mut DiagnosticsBuilder<'db, SemanticDiagnostic<'db>>, attrs: &AttributeList<'db>, ) -> Self

Trait Implementations

impl<'db> Clone for FeatureKind<'db>

fn clone(&self) -> FeatureKind<'db>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'db> Debug for FeatureKind<'db>

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

Formats the value using the given formatter.

impl<'db> PartialEq for FeatureKind<'db>

fn eq(&self, other: &FeatureKind<'db>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'db> Update for FeatureKind<'db>

unsafe fn maybe_update(old_pointer_: *mut Self, new_value_: Self) -> bool

Returns

impl<'db> Eq for FeatureKind<'db>

impl<'db> StructuralPartialEq for FeatureKind<'db>
