pub enum AliasTy<I: Interner> {
    Projection(ProjectionTy<I>),
    Opaque(OpaqueTy<I>),
}
Expand description

An alias, which is a trait indirection such as a projection or opaque type.

Variants

Projection(ProjectionTy<I>)

An associated type projection.

Opaque(OpaqueTy<I>)

An opaque type.

Implementations

Trait Implementations

Cast a value to type T.
Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
The interner associated with the type.
Feeds this value into the given Hasher. Read more
Feeds a slice of this type into the given Hasher. Read more
This method tests for self and other values to be equal, and is used by ==. Read more
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
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. Read more
A convenient alternative to try_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_fold_with. Read more
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. Read more
Uses the zipper to walk through two values, ensuring that they match.

Blanket Implementations

Gets the TypeId of self. Read more
Immutably borrows from an owned value. Read more
Mutably borrows from an owned value. Read more
Cast a value to type U using CastTo.
Checks whether self and other could possibly match.

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Shifts this term in one level of binders.
Shifts a term valid at outer_binder so that it is valid at the innermost binder. See DebruijnIndex::shifted_in_from for a detailed explanation. Read more
Shifts a term valid at the innermost binder so that it is valid at outer_binder. See DebruijnIndex::shifted_out_to for a detailed explanation. Read more
Shifts this term out one level of binders.
The resulting type after obtaining ownership.
Creates owned data from borrowed data, usually by cloning. Read more
Uses borrowed data to replace owned data, usually by cloning. Read more
The type returned in the event of a conversion error.
Performs the conversion.
The type returned in the event of a conversion error.
Performs the conversion.
Check whether there are free (non-bound) variables.
