Struct reqwest_dav::re_exports::tokio::net::unix::OwnedReadHalf

source · [−]
pub struct OwnedReadHalf { /* private fields */ }
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. If n is 0, then it can indicate one of two scenarios:

  1. The stream’s read half is closed and will no longer yield data.
  2. The specified buffer was 0 bytes in length.

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.
