Trait BlockDriverOps 

pub trait BlockDriverOps: BaseDriverOps {
    // Required methods
    fn num_blocks(&self) -> u64;
    fn block_size(&self) -> usize;
    fn read_block(&mut self, block_id: u64, buf: &mut [u8]) -> DevResult;
    fn write_block(&mut self, block_id: u64, buf: &[u8]) -> DevResult;
    fn flush(&mut self) -> DevResult;
}

Operations that require a block storage device driver to implement.

Required Methods

fn num_blocks(&self) -> u64

The number of blocks in this storage device.

The total size of the device is num_blocks() * block_size().

fn block_size(&self) -> usize

The size of each block in bytes.

fn read_block(&mut self, block_id: u64, buf: &mut [u8]) -> DevResult

Reads blocked data from the given block.

The size of the buffer may exceed the block size, in which case multiple contiguous blocks will be read.

fn write_block(&mut self, block_id: u64, buf: &[u8]) -> DevResult

Writes blocked data to the given block.

The size of the buffer may exceed the block size, in which case multiple contiguous blocks will be written.

fn flush(&mut self) -> DevResult

Flushes the device to write all pending data to the storage.
