Struct IOEvent 

pub struct IOEvent<C: IOCallback>(pub Box<IOEvent_<C>>);

Tuple Fields

0: Box<IOEvent_<C>>

Implementations

impl<C: IOCallback> IOEvent<C>

pub fn new(fd: RawFd, buf: Buffer, action: IOAction, offset: i64) -> IOEvent<C>

pub fn set_callback(&mut self, cb: C)

Set callback for IOEvent, might be closure or a custom struct

pub fn get_size(&self) -> usize

pub fn get_buf_ref<'a>(&'a self) -> &'a [u8]

pub fn is_done(&self) -> bool

pub fn get_write_result(self) -> Result<(), Errno>

pub fn get_result(&self) -> Result<usize, Errno>

Get the result of the IO operation (bytes read/written or error). Returns the number of bytes successfully transferred.

pub fn get_read_result(self) -> Result<Buffer, Errno>

Get the buffer from a read operation. Note: The buffer length is NOT modified. Use get_result() to get actual bytes read.

pub fn callback_merged(self)

For writing custom callback workers

Callback worker should always call this function on receiving IOEvent from Driver
