Trait Implementations

impl<'tcx> ArenaAllocatable<'tcx, IsNotCopy> for ExternalConstraintsData<'tcx>

fn allocate_on<'a>(self, arena: &'a Arena<'tcx>) -> &'a mut Self

fn allocate_from_iter<'a>( arena: &'a Arena<'tcx>, iter: impl IntoIterator<Item = Self> ) -> &'a mut [Self]

impl<'tcx> Borrow<ExternalConstraintsData<'tcx>> for InternedInSet<'tcx, ExternalConstraintsData<'tcx>>

fn borrow<'a>(&'a self) -> &'a ExternalConstraintsData<'tcx>

Immutably borrows from an owned value.

impl<'tcx> Clone for ExternalConstraintsData<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for ExternalConstraintsData<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> Default for ExternalConstraintsData<'tcx>

fn default() -> ExternalConstraintsData<'tcx>

Returns the “default value” for a type.

impl<'tcx> Hash for ExternalConstraintsData<'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<ExternalConstraintsData<'tcx>> for ExternalConstraintsData<'tcx>

fn eq(&self, other: &ExternalConstraintsData<'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 ExternalConstraintsData<'tcx>

impl<'tcx> StructuralEq for ExternalConstraintsData<'tcx>

impl<'tcx> StructuralPartialEq for ExternalConstraintsData<'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.
