Struct sunrise_ahci::disk::IDisk

pub struct IDisk(Arc<Mutex<Disk>>);

Interface to a disk.

Implementations

impl IDisk

pub fn new(value: Arc<Mutex<Disk>>) -> Self

Creates an IDisk from the wrapped Disk.

Trait Implementations

impl Clone for IDisk

fn clone(&self) -> IDisk

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IDisk

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl IDisk for IDisk

fn sector_count(
    &mut self,
    _work_queue: WorkQueue<'static>
) -> Result<u64, Error>

Returns the number of addressable 512-octet sectors for this disk.

fn read_dma(
    &mut self,
    _manager: WorkQueue<'static>,
    address: u64,
    out_blocks: &mut [Block]
) -> Result<(), Error>

Reads sectors from disk.

Reads sector_count sectors starting from lba.

Error

• InvalidArg:
  • mapping_size does not reflect the passed handle's size, or mapping it failed,
  • lba, sector_count, or lba + sector_count is higher than the number of addressable sectors on this disk,
  • sector_count == 0.
• BufferTooScattered:
  • The passed handle points to memory that is so physically scattered it overflows the PRDT. This can only happen for read/writes of 1985 sectors or more. You should consider retrying with a smaller sector_count.

fn write_dma(
    &mut self,
    _manager: WorkQueue<'static>,
    address: u64,
    in_blocks: &[Block]
) -> Result<(), Error>

Writes sectors to disk.

Writes sector_count sectors starting from lba.

Error

• InvalidArg:
  • mapping_size does not reflect the passed handle's size, or mapping it failed,
  • lba, sector_count, or lba + sector_count is higher than the number of addressable sectors on this disk,
  • sector_count == 0.
• BufferTooScattered:
  • The passed handle points to memory that is so physically scattered it overflows the PRDT. This can only happen for read/writes of 1985 sectors or more. You should consider retrying with a smaller sector_count.

fn dispatch(
    &'a mut self,
    manager: WorkQueue<'static>,
    cmdid: u32,
    buf: &'a mut [u8]
) -> FutureObj<'a, Result<(), Error>>

Handle an incoming IPC request.
