#[repr(C)]
pub struct BlockIO { /* fields omitted */ }
Expand description

The Block I/O protocol.

Implementations

impl BlockIO[src]

pub fn media(&self) -> &BlockIOMedia[src]

Pointer for block IO media.

pub fn reset(&mut self, extended_verification: bool) -> Result[src]

Resets the block device hardware.

Arguments

  • extended_verification Indicates that the driver may perform a more exhaustive verification operation of the device during reset.

Errors

  • uefi::Status::DEVICE_ERROR The block device is not functioning correctly and could not be reset.

pub fn read_blocks(&self, media_id: u32, lba: Lba, buffer: &mut [u8]) -> Result[src]

Read the requested number of blocks from the device.

Arguments

  • media_id - The media ID that the read request is for.
  • lba - The starting logical block address to read from on the device.
  • buffer - The target buffer of the read operation

Errors

  • uefi::Status::DEVICE_ERROR The device reported an error while attempting to perform the read operation.
  • uefi::Status::NO_MEDIA There is no media in the device.
  • uefi::Status::MEDIA_CHANGED The media_id is not for the current media.
  • uefi::Status::BAD_BUFFER_SIZE The buffer size parameter is not a multiple of the intrinsic block size of the device.
  • uefi::Status::INVALID_PARAMETER The read request contains LBAs that are not valid, or the buffer is not on proper alignment.

pub fn write_blocks(&mut self, media_id: u32, lba: Lba, buffer: &[u8]) -> Result[src]

Writes the requested number of blocks to the device.

Arguments

  • media_id The media ID that the write request is for.
  • lba The starting logical block address to be written.
  • buffer Buffer to be written

Errors

  • uefi::Status::WRITE_PROTECTED The device cannot be written to.
  • uefi::Status::NO_MEDIA There is no media in the device.
  • uefi::Status::MEDIA_CHANGED The media_id is not for the current media.
  • uefi::Status::DEVICE_ERROR The device reported an error while attempting to perform the write operation.
  • uefi::Status::BAD_BUFFER_SIZE The buffer size parameter is not a multiple of the intrinsic block size of the device.
  • uefi::Status::INVALID_PARAMETER The write request contains LBAs that are not valid, or the buffer is not on proper alignment.

pub fn flush_blocks(&mut self) -> Result[src]

Flushes all modified data to a physical block device.

Errors

  • uefi::Status::DEVICE_ERROR The device reported an error while attempting to write data.
  • uefi::Status::NO_MEDIA There is no media in the device.
