Trait CacheKey

pub trait CacheKey<M = ()>:
    Debug
    + Invalidatable<M>
    + 'static {
    // Required methods
    fn any(&self) -> &(dyn Any + 'static);
    fn any_eq(&self, other: &dyn Any) -> bool;

}

Trait for arbitrary cache keys.

Cache keys are arbitrary Rust types that are sortable and comparable.

Required Methods

fn any(&self) -> &(dyn Any + 'static)

fn any_eq(&self, other: &dyn Any) -> bool

fn any_ord(&self, other: &dyn Any) -> Ordering

fn clone_boxed(&self) -> Box<dyn CacheKey<M>>

Trait Implementations

impl<M: 'static> Clone for Box<dyn CacheKey<M>>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<M: 'static> Ord for dyn CacheKey<M>

fn cmp(&self, other: &dyn CacheKey<M>) -> Ordering

This method returns an Ordering between self and other.

impl<M: 'static> PartialEq for dyn CacheKey<M>

fn eq(&self, other: &dyn CacheKey<M>) -> 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.

impl<M: 'static> PartialOrd for dyn CacheKey<M>

fn partial_cmp(&self, other: &dyn CacheKey<M>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
