Implementations

impl GenericArgKind

pub fn expect_ty(&self) -> &Ty

Panic if this generic argument is not a type, otherwise return the type.

pub fn expect_const(&self) -> &TyConst

Panic if this generic argument is not a const, otherwise return the const.

pub fn ty(&self) -> Option<&Ty>

Return the generic argument type if applicable, otherwise return None.

Trait Implementations

impl Clone for GenericArgKind

fn clone(&self) -> GenericArgKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GenericArgKind

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

Formats the value using the given formatter.

impl PartialEq for GenericArgKind

fn eq(&self, other: &GenericArgKind) -> 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 RustcInternal for GenericArgKind

type T<'tcx> = GenericArg<'tcx>

fn internal<'tcx>( &self, tables: &mut Tables<'_>, tcx: TyCtxt<'tcx>, ) -> Self::T<'tcx>

impl Serialize for GenericArgKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Visitable for GenericArgKind

fn super_visit<V: Visitor>(&self, visitor: &mut V) -> ControlFlow<V::Break>

fn visit<V: Visitor>(&self, visitor: &mut V) -> ControlFlow<V::Break>

impl Eq for GenericArgKind

impl StructuralPartialEq for GenericArgKind

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.
