Struct UefiBlockIo

pub struct UefiBlockIo {
    protocol: *mut BlockIoProtocol,
    block_size: BlockSize,
    num_blocks: u64,
}

Wrapper around UEFI BlockIoProtocol implementing gpt_disk_io::BlockIo

Fields

protocol: *mut BlockIoProtocol

block_size: BlockSize

num_blocks: u64

Implementations

impl UefiBlockIo

pub unsafe fn new(protocol: *mut BlockIoProtocol) -> Self

Create a new wrapper

Safety

The protocol pointer must be valid for the lifetime of this wrapper.

pub fn protocol(&self) -> *mut BlockIoProtocol

Get the underlying protocol pointer

pub fn block_size_bytes(&self) -> u32

Get block size as u32

pub fn total_blocks(&self) -> u64

Get total number of blocks

Trait Implementations

impl BlockIo for UefiBlockIo

type Error = UefiBlockIoError

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, buffer: &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, buffer: &[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.
