Type Alias ConstrainedSubst

pub type ConstrainedSubst = ConstrainedSubst<Interner>;

Aliased Type

struct ConstrainedSubst {
    pub subst: Substitution<Interner>,
    pub constraints: Constraints<Interner>,
}

Fields

subst: Substitution<Interner>

The substitution that is being constrained.

NB: The is_trivial routine relies on the fact that subst is folded first.

constraints: Constraints<Interner>

Region constraints that constrain the substitution.

Trait Implementations

impl<I> Clone for ConstrainedSubst<I>

where I: Clone + Interner,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> Debug for ConstrainedSubst<I>

where I: Debug + Interner,

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

Formats the value using the given formatter.

impl<I> Display for ConstrainedSubst<I>

where I: Interner,

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

Formats the value using the given formatter.

impl<I> HasInterner for ConstrainedSubst<I>

where I: Interner,

type Interner = I

The interner associated with the type.

impl<I> Hash for ConstrainedSubst<I>

where I: Hash + Interner,

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

where __H: Hasher,

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> PartialEq for ConstrainedSubst<I>

where I: PartialEq + Interner,

fn eq(&self, other: &ConstrainedSubst<I>) -> 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<I> TypeFoldable<I> for ConstrainedSubst<I>

where I: Interner,

fn try_fold_with<E>( self, folder: &mut dyn FallibleTypeFolder<I, Error = E>, outer_binder: DebruijnIndex, ) -> Result<ConstrainedSubst<I>, 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, Error = Infallible>, 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> TypeVisitable<I> for ConstrainedSubst<I>

where I: Interner,

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> Eq for ConstrainedSubst<I>

where I: Eq + Interner,

impl<I> StructuralPartialEq for ConstrainedSubst<I>

where I: Interner,
