is one where all free inference
variables have been rewritten to “canonical vars”. These are
numbered starting from 0 in order of first appearance.

sourcepub fn unchecked_map<W>(self, map_op: impl FnOnce(V) -> W) -> Canonical<I, W>
pub fn unchecked_map<W>(self, map_op: impl FnOnce(V) -> W) -> Canonical<I, W>
Allows you to map the value
of a canonical while keeping the
same set of bound variables.
WARNING: This function is very easy to mis-use, hence the
name! In particular, the new value W
must use all the
same type/region variables in precisely the same order
as the original! (The ordering is defined by the
TypeFoldable
implementation of the type in question.)
An example of a correct use of this:
let a: Canonical<I, T> = ...;
let b: Canonical<I, (T,)> = a.unchecked_map(|v| (v, ));
An example of an incorrect use of this:
let a: Canonical<I, T> = ...;
let ty: Ty<I> = ...;
let b: Canonical<I, (T, Ty<I>)> = a.unchecked_map(|v| (v, ty));
sourcepub fn unchecked_rebind<W>(self, value: W) -> Canonical<I, W>
pub fn unchecked_rebind<W>(self, value: W) -> Canonical<I, W>
Allows you to map the value
of a canonical while keeping the same set of
bound variables.
WARNING: This function is very easy to mis-use, hence the name! See the comment of Canonical::unchecked_map for more details.

with self.value
to get
a value V that is expressed in terms of the same canonical

of self
). Apply the instantiation var_values
to this value
V, replacing each of the canonical variables.
