Implementations

impl<'tcx> FieldDef

fn uninhabited_from(
    &self,
    tcx: TyCtxt<'tcx>,
    substs: SubstsRef<'tcx>,
    is_enum: bool,
    param_env: ParamEnv<'tcx>
) -> DefIdForest

Calculates the forest of DefIds from which this field is visibly uninhabited.

impl<'tcx> FieldDef

pub fn ty(&self, tcx: TyCtxt<'tcx>, subst: SubstsRef<'tcx>) -> Ty<'tcx>

Returns the type of this field. The subst is typically obtained via the second field of TyKind::AdtDef.

Trait Implementations

impl Debug for FieldDef

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

Formats the value using the given formatter.

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

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

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
