Expand description

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§

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)?;

This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
