Expand description

Trait for writing new layers.

Required Methods§

Source

fn write( &mut self, item: ItemRef<'_, K, V>, ) -> impl Future<Output = Result<(), Error>> + Send

Writes the given item to this layer.

Source

fn flush(&mut self) -> impl Future<Output = Result<(), Error>> + Send

Flushes any buffered items to the backing storage.

Source

fn bytes_written(&self) -> u64

Returns the total bytes written to the layer.

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.
