Struct varu64::LimitedReader

pub struct LimitedReader<R> { /* fields omitted */ }

Wraps a reader and limits the number of bytes that can be read from it. Once the limit has been reached, further calls to poll_read will return Ok(Ready(0)).

Methods

impl<R> LimitedReader<R>

pub fn new(inner: R, limit: usize) -> LimitedReader<R>

Create a new LimitedReader, wrapping the given reader.

Trait Implementations

impl<R: AsyncRead> AsyncRead for LimitedReader<R>

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

Attempt to read from the AsyncRead into buf.

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.
