Trait InvalidationReason 

pub trait InvalidationReason:
    DynEq
    + DynHash
    + Display
    + Send
    + Sync
    + 'static {
    // Provided method
    fn kind(&self) -> Option<StaticOrArc<dyn InvalidationReasonKind>> { ... }
}

A user-facing reason why a task was invalidated. This should only be used for invalidation that were triggered by the user.

Reasons are deduplicated, so this need to implement Eq and Hash

Provided Methods

fn kind(&self) -> Option<StaticOrArc<dyn InvalidationReasonKind>>

Trait Implementations

impl Eq for dyn InvalidationReason

impl Hash for dyn InvalidationReason

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

Feeds this value into the given Hasher.

impl PartialEq for dyn InvalidationReason

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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
