Required Methods

fn get_or_fetch<'life0, 'async_trait, K, V, F, Fut>( &'life0 mut self, key: K, data_loader: F, expire_seconds: usize, ) -> Pin<Box<dyn Future<Output = Result<V>> + Send + 'async_trait>>

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.
