Struct chalk_solve::coherence::SpecializationPriorities

source · 
pub struct SpecializationPriorities<I: Interner> {
    map: IndexMap<ImplId<I>, SpecializationPriority>,
}
Expand description

Stores the specialization priorities for a set of impls. This basically encodes which impls specialize one another.

Fields§

§map: IndexMap<ImplId<I>, SpecializationPriority>

Implementations§

source§

impl<I: Interner> SpecializationPriorities<I>

source

pub fn new() -> Self

source

pub fn priority(&self, impl_id: ImplId<I>) -> SpecializationPriority

Lookup the priority of an impl in the set (panics if impl is not in set).

source

fn insert(&mut self, impl_id: ImplId<I>, p: SpecializationPriority)

Store the priority of an impl (used during construction). Panics if we have already stored the priority for this impl.

impl<I: PartialEq + Interner> PartialEq for SpecializationPriorities<I>

source§

fn eq(&self, other: &SpecializationPriorities<I>) -> bool

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
