Struct quiche::Header

pub struct Header {
    pub ty: Type,
    pub version: u32,
    pub dcid: Vec<u8>,
    pub scid: Vec<u8>,
    pub odcid: Option<Vec<u8>>,
    pub token: Option<Vec<u8>>,
    pub versions: Option<Vec<u32>>,
    // some fields omitted
}

A QUIC packet's header.

Fields

ty: Type

The type of the packet.

version: u32

The version of the packet.

dcid: Vec<u8>

The destination connection ID of the packet.

scid: Vec<u8>

The source connection ID of the packet.

odcid: Option<Vec<u8>>

The original destination connection ID. Only present in Retry packets.

token: Option<Vec<u8>>

The address verification token of the packet. Only present in Initial and Retry packets.

versions: Option<Vec<u32>>

The list of versions in the packet. Only present in VersionNegotiation packets.

Methods

impl Header

pub fn from_slice(buf: &mut [u8], dcid_len: usize) -> Result<Header>

Parses a QUIC packet header from the given buffer.

The dcid_len parameter is the length of the destination connection ID, required to parse short header packets.

Examples:

let (len, src) = socket.recv_from(&mut buf).unwrap();

let hdr = quiche::Header::from_slice(&mut buf[..len], LOCAL_CONN_ID_LEN)?;

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl PartialEq<Header> for Header

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
