Struct timely_communication::networking::MessageHeader

pub struct MessageHeader {
    pub channel: usize,
    pub source: usize,
    pub target: usize,
    pub length: usize,
    pub seqno: usize,
}

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.

Methods

impl MessageHeader

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

Returns a header when there is enough supporting data

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

Writes the header as binary data.

pub fn required_bytes(&self) -> usize

The number of bytes required for the header and data.

unsafe fn entomb<W: Write>(&self, _write: &mut W) -> Result<()>

Write any additional information about &self beyond its binary representation.

fn extent(&self) -> usize

Reports the number of further bytes required to entomb self.
