Required Methods

fn insert_if_changed<'a>( &'a mut self, k: E::Key, v: E, track: &'a E::TrackCtx, ) -> BoxFuture<'a, Result<()>>

fn insert_all_if_changed<'a, I>( &'a mut self, iter: I, track: &'a E::TrackCtx, ) -> BoxFuture<'a, Result<usize>>

where I: IntoIterator<Item = (E::Key, E)> + Send + 'a, I::IntoIter: Send,

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.
