Struct PacketHeader 

pub struct PacketHeader {
    pub length: u32,
    pub checksum: u32,
    pub token: UID,
}

Packet header for wire format.

Contains the fixed-size header fields that precede the payload.

Fields

length: u32

Total packet size including header.

checksum: u32

CRC32C checksum of (token + payload).

token: UID

Destination endpoint token.

Implementations

impl PacketHeader

pub fn serialize_into(&self, buf: &mut [u8])

Serialize header into buffer (must be at least HEADER_SIZE bytes).

Panics

Panics if buffer is smaller than HEADER_SIZE.

pub fn deserialize(buf: &[u8]) -> Result<Self, WireError>

Deserialize header from buffer.

Errors

Returns InsufficientData if buffer is smaller than HEADER_SIZE.

Trait Implementations

impl Clone for PacketHeader

fn clone(&self) -> PacketHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PacketHeader

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

Formats the value using the given formatter.

impl PartialEq for PacketHeader

fn eq(&self, other: &PacketHeader) -> 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.
