Expand description

Framing data for each Vec<u8> transmission, indicating a typed channel, the source and destination workers, and the length in bytes.

Fields§

§channel: usize

index of channel.

§source: usize

index of worker sending message.

§target: usize

index of worker receiving message.

§length: usize

number of bytes in message.

§seqno: usize

sequence number.

Implementations§

source§

impl MessageHeader

source

pub fn try_read(bytes: &mut [u8]) -> Option<MessageHeader>

source

pub fn write_to<W: Write>(&self, writer: &mut W) -> Result<()>

Writes the header as binary data.

source

pub fn required_bytes(&self) -> usize

The number of bytes required for the header and data.
