Struct Header

pub struct Header<'a> {
    pub ty: Type,
    pub version: u32,
    pub dcid: ConnectionId<'a>,
    pub scid: ConnectionId<'a>,
    pub token: Option<Vec<u8>>,
    pub versions: Option<Vec<u32>>,
    /* private fields */
}

A QUIC packet’s header.

Fields

ty: Type

The type of the packet.

version: u32

The version of the packet.

dcid: ConnectionId<'a>

The destination connection ID of the packet.

scid: ConnectionId<'a>

The source connection ID of the packet.

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.

Implementations

impl<'a> Header<'a>

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

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<'a> Clone for Header<'a>

fn clone(&self) -> Header<'a>

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<'a> PartialEq for Header<'a>

fn eq(&self, other: &Header<'a>) -> 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.
