Struct RtpHeader 

pub struct RtpHeader {
    pub payload_type: u8,
    pub marker: bool,
    pub sequence: u16,
    pub timestamp: u32,
    pub ssrc: u32,
}

The RFC 3550 fixed header fields a packetizer chooses per packet.

Fields

payload_type: u8

7-bit payload type (a static PT like 0 = PCMU, or a dynamic 96..=127).

marker: bool

Frame/talkspurt boundary marker; payload-format-defined semantics.

sequence: u16

Per-packet sequence number (the packetizer increments, wrapping).

timestamp: u32

Media-clock timestamp of the payload’s sampling instant.

ssrc: u32

Synchronization source identifier.

Implementations

impl RtpHeader

pub fn parse(buf: &[u8]) -> Option<RtpParsed>

Parse an RTP datagram received from an arbitrary peer, returning the fixed-header fields and the payload’s byte range. The inverse of to_bytes, but tolerant of the header variations a real sender may set that to_bytes never emits: a CSRC list (CC), a profile extension header (X), and payload padding (P).

Parser discipline (never trust the wire, per the demuxer rule): every offset and length is folded with checked arithmetic and bounds-checked against buf, so a malformed or truncated datagram returns None rather than panicking or reading out of bounds. A non-RTP-v2 packet is rejected. Heap-free (part of the no-alloc subset), so an MCU RTP source uses it directly.

pub fn parse_header(buf: &[u8]) -> Option<RtpParsedHeader>

Parse the authenticated RTP header without reading the payload. This accepts CSRC identifiers and an RTP extension and rejects any header whose declared fields exceed buf.

pub const fn to_bytes(self) -> [u8; 12]

The header as it goes on the wire. Pure and heap-free; a packetizer prepends this to its payload.
