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.

Implementations

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>(&self, writer: &mut W) -> Result<(), Error>

where W: Write,

Writes the header as binary data.

pub fn required_bytes(&self) -> usize

The number of bytes required for the header and data.

Trait Implementations

impl Clone for MessageHeader

fn clone(&self) -> MessageHeader

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MessageHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageHeader

fn deserialize<__D>( __deserializer: __D, ) -> Result<MessageHeader, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for MessageHeader

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MessageHeader

fn eq(&self, other: &MessageHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for MessageHeader

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
