Methods for writing chunks from storage.

Required Methods

fn get_mut(&mut self, key: ChunkKey<N>) -> Option<&mut Ch>

Mutably borrow the chunk at key.

fn get_mut_or_insert_with( &mut self, key: ChunkKey<N>, create_chunk: impl FnOnce() -> Ch, ) -> &mut Ch

Mutably borrow the chunk at key. If it doesn’t exist, insert the return value of create_chunk.

fn replace(&mut self, key: ChunkKey<N>, chunk: Ch) -> Option<Ch>

Replace the chunk at key with chunk, returning the old value.

fn write(&mut self, key: ChunkKey<N>, chunk: Ch)

Overwrite the chunk at key with chunk. Drops the previous value.

fn delete(&mut self, key: ChunkKey<N>)

Removes and drops the chunk at key.

fn pop(&mut self, key: ChunkKey<N>) -> Option<Ch>

Removes and returns the chunk at key.

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.
