Enum FixpointQueryKind

pub enum FixpointQueryKind {
    Impl,
    Body,
    Invariant,
}

The different reasons we issue fixpoint queries. This is used to dissambiguate queries that are issued for the same item.

NOTE: This is defined here because it’s also used in timings

Variants

Impl

Query issued when checking an impl method is a subtype of the trait

Body

Query issued to check the body of a function

Invariant

Query issued to check an (enum) invariant is implied by the type definition
