Enum Nothing 

pub enum Nothing {}

No disk: memory over nothing never waits.

Trait Implementations

impl Backend for Nothing

type Lock = ()

async fn lock(&self) -> Result<(), String>

The one exclusive lock over these names, shared by every store over them.

async fn get(&self, _: &str) -> Result<Option<Vec<u8>>, String>

async fn get_range( &self, _: &str, _: u64, _: u64, ) -> Result<Option<Vec<u8>>, String>

At most len bytes from from on, fewer where the name ends sooner.

async fn put(&self, _: &str, _: &[u8]) -> Result<(), String>

async fn delete(&self, _: &str) -> Result<bool, String>

False where another holder has name open, so it stays.

async fn list(&self) -> Result<Vec<(String, u64)>, String>

Each name, with its size in bytes.

async fn staging(&self) -> Result<Nothing, String>

An area beside these names that no other store writes and list never names.

async fn rename(&self, _: &str, _: &Nothing) -> Result<bool, String>

name moved from here into to in one step, over whatever to held under it; as delete, false where either is open.
