Constants.

Fields

interned: I::InternedConst

Implementations

Create a Const using something that can be cast to const data.

Gets the interned constant.

Gets the constant data from the interner.

If this is a ConstData::BoundVar(d), returns Some(d) else None.

If this is a ConstData::InferenceVar(d), returns Some(d) else None.

True if this const is a “bound” const, and hence needs to be shifted across binders. Meant for debug assertions.

“Folding” a const invokes the fold_const method on the folder; this usually (in turn) invokes super_fold_const to fold the individual parts.

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
Recursively folds the value.
A convenient alternative to try_super_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_super_fold_with. Read more
Recursively visits the type contents.
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.

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
