Trait Implementations

impl<I: Clone + Interner> Clone for OpaqueTyId<I>

where I::DefId: Clone,

fn clone(&self) -> OpaqueTyId<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I: Interner> Debug for OpaqueTyId<I>

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

Formats the value using the given formatter.

impl<I: Hash + Interner> Hash for OpaqueTyId<I>

where I::DefId: Hash,

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<I: Ord + Interner> Ord for OpaqueTyId<I>

where I::DefId: Ord,

fn cmp(&self, other: &OpaqueTyId<I>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<I: PartialEq + Interner> PartialEq for OpaqueTyId<I>

where I::DefId: PartialEq,

fn eq(&self, other: &OpaqueTyId<I>) -> 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<I: PartialOrd + Interner> PartialOrd for OpaqueTyId<I>

where I::DefId: PartialOrd,

fn partial_cmp(&self, other: &OpaqueTyId<I>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<I: Interner> TypeFoldable<I> for OpaqueTyId<I>

fn try_fold_with<E>( self, _folder: &mut dyn FallibleTypeFolder<I, Error = E>, _outer_binder: DebruijnIndex, ) -> Result<Self, E>

Apply the given folder folder to self; binders is the number of binders that are in scope when beginning the folder. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs.

fn fold_with( self, folder: &mut dyn TypeFolder<I>, outer_binder: DebruijnIndex, ) -> Self

A convenient alternative to try_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_fold_with.

impl<I: Interner> TypeVisitable<I> for OpaqueTyId<I>

fn visit_with<B>( &self, _visitor: &mut dyn TypeVisitor<I, BreakTy = B>, _outer_binder: DebruijnIndex, ) -> ControlFlow<B>

Apply the given visitor visitor to self; binders is the number of binders that are in scope when beginning the visitor. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs.

impl<I: Interner> Zip<I> for OpaqueTyId<I>

fn zip_with<Z: Zipper<I>>( _zipper: &mut Z, _variance: Variance, a: &Self, b: &Self, ) -> Fallible<()>

Uses the zipper to walk through two values, ensuring that they match.

impl<I: Copy + Interner> Copy for OpaqueTyId<I>

where I::DefId: Copy,

impl<I: Eq + Interner> Eq for OpaqueTyId<I>

where I::DefId: Eq,
