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.

Implementations

source

impl<T: HasInterner> UCanonical<T>

source

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).

source

pub fn trivial_substitution(
&self,
interner: T::Interner
) -> Substitution<T::Interner>

Creates an identity substitution.
