Struct chalk_ir::UCanonical
source · [−]pub struct UCanonical<T: HasInterner> {
pub canonical: Canonical<T>,
pub universes: usize,
}
Expand description
A “universe canonical” value. This is a wrapper around a
Canonical
, indicating that the universes within have been
“renumbered” to start from 0 and collapse unimportant
distinctions.
To produce one of these values, use the u_canonicalize
method.
Fields
canonical: Canonical<T>
The wrapped Canonical
.
universes: usize
The number of universes that have been collapsed.

) -> bool
pub fn is_trivial_substitution(
&self,
interner: T::Interner,
canonical_subst: &Canonical<AnswerSubst<T::Interner>>
) -> bool
Checks whether the universe canonical value is a trivial substitution (e.g. an identity substitution).

&self,
interner: T::Interner
) -> Substitution<T::Interner>
pub fn trivial_substitution(
&self,
interner: T::Interner
) -> Substitution<T::Interner>
Creates an identity substitution.
