Struct chalk_ir::Canonical [−][src]
pub struct Canonical<T: HasInterner> { pub value: T, pub binders: CanonicalVarKinds<T::Interner>, }
Expand description
Wraps a “canonicalized item”. Items are canonicalized as follows:
All unresolved existential variables are “renumbered” according to their
first appearance; the kind/universe of the variable is recorded in the
binders
field.
Fields
value: T
The item that is canonicalized.
binders: CanonicalVarKinds<T::Interner>
The kind/universe of the variable.
Implementations
Display the canonicalized item.
Trait Implementations
impl<T, U> CastTo<Canonical<U>> for Canonical<T> where
T: CastTo<U> + HasInterner,
U: HasInterner<Interner = T::Interner>,
[src]
impl<T, U> CastTo<Canonical<U>> for Canonical<T> where
T: CastTo<U> + HasInterner,
U: HasInterner<Interner = T::Interner>,
[src]impl<I, T> Fold<I> for Canonical<T> where
I: Interner,
T: HasInterner<Interner = I> + Fold<I>,
<T as Fold<I>>::Result: HasInterner<Interner = I>,
[src]
impl<I, T> Fold<I> for Canonical<T> where
I: Interner,
T: HasInterner<Interner = I> + Fold<I>,
<T as Fold<I>>::Result: HasInterner<Interner = I>,
[src]The type of value that will be produced once folding is done.
Typically this is Self
, unless Self
contains borrowed
values, in which case owned values are produced (for example,
one can fold over a &T
value where T: Fold
, in which case
you get back a T
, not a &T
). 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

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
