Required Methods

fn ts_gen( &'lock self, key: &'lock <Self as ThreadSafeGenCacheStore<'lock>>::Key, args: Self::Args, ) -> <Self as ThreadSafeGenCacheStore<'lock>>::Value

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

fn ts_get_or_gen( &'lock self, key: &'lock <Self as ThreadSafeGenCacheStore<'lock>>::Key, args: Self::Args, ) -> <Self as ThreadSafeGenCacheStore<'lock>>::Value

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

fn ts_get_or_new( &'lock self, key: &'lock <Self as ThreadSafeGenCacheStore<'lock>>::Key, args: Self::Args, ) -> <Self as ThreadSafeGenCacheStore<'lock>>::Value

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

fn ts_gen_new( &'lock self, key: &'lock <Self as ThreadSafeGenCacheStore<'lock>>::Key, args: Self::Args, ) -> <Self as ThreadSafeGenCacheStore<'lock>>::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.
