Trait Backend

pub trait Backend {
    // Required methods
    fn get_data(&mut self) -> BackendResult<Vec<u8>>;
    fn put_data(&mut self, data: &[u8]) -> BackendResult<()>;
}

The Backend Trait.

It should always read and save in full the data that it is passed. This means that a write to the backend followed by a read must return the same dataset.

Important: You can only return custom errors if the other_errors feature is enabled

Required Methods

fn get_data(&mut self) -> BackendResult<Vec<u8>>

Read the all data from the backend.

fn put_data(&mut self, data: &[u8]) -> BackendResult<()>

Write the whole slice to the backend.

Trait Implementations

impl Backend for Box<dyn Backend>

fn get_data(&mut self) -> BackendResult<Vec<u8>>

Read the all data from the backend.

fn put_data(&mut self, data: &[u8]) -> BackendResult<()>

Write the whole slice to the backend.
