Enum rustc_mir_transform::gvn::AggregateTy

enum AggregateTy<'tcx> {
    Array,
    Tuple,
    Def(DefId, GenericArgsRef<'tcx>),
    RawPtr {
        data_pointer_ty: Ty<'tcx>,
        output_pointer_ty: Ty<'tcx>,
    },
}

Computing the aggregate’s type can be quite slow, so we only keep the minimal amount of information to reconstruct it when needed.

Variants

Array

Invariant: this must not be used for an empty array.

Tuple

Def(DefId, GenericArgsRef<'tcx>)

RawPtr

Fields

data_pointer_ty: Ty<'tcx>

Needed for cast propagation.

output_pointer_ty: Ty<'tcx>

The data pointer can be anything thin, so doesn’t determine the output.

Trait Implementations

impl<'tcx> Clone for AggregateTy<'tcx>

fn clone(&self) -> AggregateTy<'tcx>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for AggregateTy<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> Hash for AggregateTy<'tcx>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'tcx> PartialEq for AggregateTy<'tcx>

fn eq(&self, other: &AggregateTy<'tcx>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<'tcx> Eq for AggregateTy<'tcx>

impl<'tcx> StructuralPartialEq for AggregateTy<'tcx>

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.
