Struct tokio_io::codec::length_delimited::FramedWrite [] [src]

pub struct FramedWrite<T, B: IntoBuf = BytesMut> { /* fields omitted */ }

Adapts a byte stream to a Sink accepting entire frame values.

See module level documentation for more detail.

Methods

impl<T: AsyncWrite, B: IntoBuf> FramedWrite<T, B>
[src]

Important traits for FramedWrite<T, B>
[src]

Creates a new FramedWrite with default configuration values.

impl<T, B: IntoBuf> FramedWrite<T, B>
[src]

[src]

Returns the current max frame setting

This is the largest size this codec will write to the wire. Larger frames will be rejected.

[src]

Updates the max frame setting.

The change takes effect the next time a frame is encoded. In other words, if a frame is currently in process of being encoded with a frame size greater than val but less than the max frame length in effect before calling this function, then the frame will be allowed.

[src]

Returns a reference to the underlying I/O stream wrapped by FramedWrite.

Note that care should be taken to not tamper with the underlying stream of data coming in as it may corrupt the stream of frames otherwise being worked with.

[src]

Returns a mutable reference to the underlying I/O stream wrapped by FramedWrite.

Note that care should be taken to not tamper with the underlying stream of data coming in as it may corrupt the stream of frames otherwise being worked with.

[src]

Consumes the FramedWrite, returning its underlying I/O stream.

Note that care should be taken to not tamper with the underlying stream of data coming in as it may corrupt the stream of frames otherwise being worked with.
