Struct MemoryBlockDevice

struct MemoryBlockDevice {
    data: Vec<u8>,
}

In-memory block device for ISO data

Fields

data: Vec<u8>

Implementations

impl MemoryBlockDevice

fn new(data: Vec<u8>) -> Self

Trait Implementations

impl BlockIo for MemoryBlockDevice

type Error = MemoryBlockIoError

IO error type.

fn block_size(&self) -> BlockSize

Get the [BlockSize]. The return value is not allowed to change.

fn num_blocks(&mut self) -> Result<u64, Self::Error>

Get the number of logical blocks in the disk.

fn read_blocks( &mut self, start_lba: Lba, dst: &mut [u8], ) -> Result<(), Self::Error>

Read contiguous blocks from the disk. The dst buffer size must be a multiple of block_size. Implementations are permitted to panic if this precondition is not met, e.g. by calling [BlockSize::assert_valid_block_buffer].

fn write_blocks( &mut self, _start_lba: Lba, _src: &[u8], ) -> Result<(), Self::Error>

Write contiguous block to the disk. The src buffer size must be a multiple of block_size. Implementations are permitted to panic if this precondition is not met, e.g. by calling [BlockSize::assert_valid_block_buffer].

fn flush(&mut self) -> Result<(), Self::Error>

Flush any pending writes to the device.
