Struct Header 

pub struct Header {
    pub version: u8,
    pub padding: bool,
    pub extension: bool,
    pub marker: bool,
    pub payload_type: u8,
    pub sequence_number: u16,
    pub timestamp: u32,
    pub ssrc: u32,
    pub csrc: Vec<u32>,
    pub extension_profile: u16,
    pub extensions: Vec<Extension>,
    pub extensions_padding: usize,
}

Header represents an RTP packet header NOTE: PayloadOffset is populated by Marshal/Unmarshal and should not be modified

Fields

version: u8

The RTP version, always 2.

padding: bool

Whether the payload is followed by padding octets, the last giving the padding length.

extension: bool

Whether a header-extension block follows the fixed header.

marker: bool

The marker bit: the last packet of a video frame, or the start of a talk spurt for audio.

payload_type: u8

The payload type, which identifies the codec as negotiated in SDP.

sequence_number: u16

Increments by one per packet sent; used to detect loss and restore order.

timestamp: u32

The sampling instant of the first octet, in the codec’s clock rate.

ssrc: u32

The synchronization source — the identifier of the stream this packet belongs to.

csrc: Vec<u32>

The contributing sources, listed when a mixer combined several streams.

extension_profile: u16

Which header-extension form is in use: EXTENSION_PROFILE_ONE_BYTE or EXTENSION_PROFILE_TWO_BYTE.

extensions: Vec<Extension>

The header extensions present on this packet.

extensions_padding: usize

Padding bytes appended to the extension block so it ends on a 32-bit boundary.

Implementations

impl Header

pub fn get_extension_payload_len(&self) -> usize

The total encoded length of the extension payloads, padding excluded.

pub fn set_extension(&mut self, id: u8, payload: Bytes) -> Result<()>

SetExtension sets an RTP header extension

pub fn get_extension_ids(&self) -> Vec<u8>

returns an extension id array

pub fn get_extension(&self, id: u8) -> Option<Bytes>

returns an RTP header extension

pub fn del_extension(&mut self, id: u8) -> Result<()>

Removes an RTP Header extension

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate 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 Default for Header

fn default() -> Header

Returns the “default value” for a type.

impl Eq for Header

impl Marshal for Header

fn marshal_to(&self, buf: &mut [u8]) -> Result<usize>

Marshal serializes the header and writes to the buffer.

fn marshal(&self) -> Result<BytesMut, Error>

Encodes into a freshly allocated buffer sized by MarshalSize::marshal_size.

impl MarshalSize for Header

fn marshal_size(&self) -> usize

MarshalSize returns the size of the packet once marshaled.

impl PartialEq for Header

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Header

impl Unmarshal for Header

fn unmarshal<B>(raw_packet: &mut B) -> Result<Self>

where Self: Sized, B: Buf,

Unmarshal parses the passed byte slice and stores the result in the Header this method is called upon
