Struct tokio::net::unix::OwnedReadHalf [−][src]
pub struct OwnedReadHalf { /* fields omitted */ }Expand description
Owned read half of a UnixStream, created by into_split.
Reading from an OwnedReadHalf is usually done using the convenience methods found
on the AsyncReadExt trait.
Implementations
Attempts to put the two halves of a UnixStream back together and
recover the original socket. Succeeds only if the two halves
originated from the same call to into_split.
Waits for any of the requested ready states.
This function is usually paired with try_read() or try_write(). It
can be used to concurrently read / write to the same socket on a single
task without splitting the socket.
Cancel safety
This method is cancel safe. Once a readiness event occurs, the method
will continue to return immediately until the readiness event is
consumed by an attempt to read or write that fails with WouldBlock or
Poll::Pending.
Waits for the socket to become readable.
This function is equivalent to ready(Interest::READABLE) and is usually
paired with try_read().
Cancel safety
This method is cancel safe. Once a readiness event occurs, the method
will continue to return immediately until the readiness event is
consumed by an attempt to read that fails with WouldBlock or
Poll::Pending.
Tries to read data from the stream into the provided buffer, returning how many bytes were read.
Receives any pending data from the socket but does not wait for new data
to arrive. On success, returns the number of bytes read. Because
try_read() is non-blocking, the buffer does not have to be stored by
the async task and can exist entirely on the stack.
Usually, readable() or ready() is used with this function.
Return
If data is successfully read, Ok(n) is returned, where n is the
number of bytes read. Ok(0) indicates the stream’s read half is closed
and will no longer yield data. If the stream is not ready to read data
Err(io::ErrorKind::WouldBlock) is returned.
Tries to read data from the stream into the provided buffer, advancing the buffer’s internal cursor, returning how many bytes were read.
Receives any pending data from the socket but does not wait for new data
to arrive. On success, returns the number of bytes read. Because
try_read_buf() is non-blocking, the buffer does not have to be stored by
the async task and can exist entirely on the stack.
Usually, readable() or ready() is used with this function.
Return
If data is successfully read, Ok(n) is returned, where n is the
number of bytes read. Ok(0) indicates the stream’s read half is closed
and will no longer yield data. If the stream is not ready to read data
Err(io::ErrorKind::WouldBlock) is returned.
Tries to read data from the stream into the provided buffers, returning how many bytes were read.
Data is copied to fill each buffer in order, with the final buffer
written to possibly being only partially filled. This method behaves
equivalently to a single call to try_read() with concatenated
buffers.
Receives any pending data from the socket but does not wait for new data
to arrive. On success, returns the number of bytes read. Because
try_read_vectored() is non-blocking, the buffer does not have to be
stored by the async task and can exist entirely on the stack.
Usually, readable() or ready() is used with this function.
Return
If data is successfully read, Ok(n) is returned, where n is the
number of bytes read. Ok(0) indicates the stream’s read half is closed
and will no longer yield data. If the stream is not ready to read data
Err(io::ErrorKind::WouldBlock) is returned.
Returns the socket address of the remote half of this connection.
Returns the socket address of the local half of this connection.
