Struct async_ringbuffer::Reader

pub struct Reader(_);

Read access to a nonblocking ring buffer with fixed capacity.

If there is no data in the buffer to read from, the current task is parked and notified once data becomes available.

Trait Implementations

impl Drop for Reader

fn drop(&mut self)

Executes the destructor for this type.

impl AsyncRead for Reader

fn poll_read(&mut self, cx: &mut Context, buf: &mut [u8]) -> Poll<usize, Error>

Read data from the RingBuffer.

This only returns Ok(Ready(0)) if either buf.len() == 0, poll_close was called on the corresponding Writer and all buffered data has been read, or if the corresponding Writer has been dropped.

Errors

This never emits an error.

unsafe fn initializer(&self) -> Initializer

Determines if this AsyncReader can work with buffers of uninitialized memory.

fn poll_vectored_read(
    &mut self,
    cx: &mut Context,
    vec: &mut [&mut IoVec]
) -> Result<Async<usize>, Error>

Attempt to read from the AsyncRead into vec using vectored IO operations.
