Trait LayerWriter 

pub trait LayerWriter<K, V>: Sized
where
    K: Debug + Send + Versioned + Sync,
    V: Debug + Send + Versioned + Sync,
{
    // Required methods
    fn write(
        &mut self,
        item: ItemRef<'_, K, V>,
    ) -> impl Future<Output = Result<(), Error>> + Send;
    fn complete(self) -> impl Future<Output = Result<u64, Error>> + Send;
}

Trait for writing new layers.

Required Methods

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

Writes the given item to this layer.

fn complete(self) -> impl Future<Output = Result<u64, Error>> + Send

Flushes any buffered items to the backing storage. The total number of bytes written is returned.

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.
