Invalidation reason kind. This is used to merge multiple reasons of the same kind into a combined description.

Reason kinds are used a hash map key, so this need to implement Eq and Hash

Required Methods

fn fmt( &self, data: &FxIndexSet<StaticOrArc<dyn InvalidationReason>>, f: &mut Formatter<'_>, ) -> Result

Displays a description of multiple invalidation reasons of the same kind. It is only called with two or more reasons.

Trait Implementations

impl Hash for dyn InvalidationReasonKind

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

impl PartialEq for dyn InvalidationReasonKind

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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