Required Methods

fn gen( &self, key: impl Borrow<<Self as GenCacheStore>::Key>, args: Self::Args, ) -> <Self as GenCacheStore>::Value

Generate a new value without checking cache or adding the value to it.

fn get_or_gen( &self, key: impl Borrow<<Self as GenCacheStore>::Key>, args: Self::Args, ) -> <Self as GenCacheStore>::Value

Get the value from cache or generate a new one without adding it.

fn get_or_new( &mut self, key: impl Borrow<<Self as GenCacheStore>::Key>, args: Self::Args, ) -> <Self as GenCacheStore>::Value

Get the value from cache or generate a new one adding it.

fn gen_new( &mut self, key: impl Borrow<<Self as GenCacheStore>::Key>, args: Self::Args, ) -> <Self as GenCacheStore>::Value

Generate a new value without checking cache and add the value to it, possibly overwriting previous values.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
