) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, Self::Error>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
[src]Read all data from the backend.
Errors
If the bytes failed to be read by the backend, an error variant is returned.

&'life0 mut self,
data: Vec<u8>
) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>> where

) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
[src]Overwrite the backend with the given data.
Errors
If the bytes failed to be written to the backend, an error variant is returned. This may mean the backend is now corrupted.
