HeaderExtension

Struct HeaderExtension 

Source
pub struct HeaderExtension<'a> {
    pub profile_id: u16,
    pub data: &'a [u8],
}
Expand description

The RTP generic header extension (§5.3.1): a 16-bit profile-specific identifier + opaque profile-specific data.

The data bytes are genuinely opaque at this layer — RFC 3550 itself defines no further structure (“the actual format of the extension is specified by the profile”). This mirrors the project’s precedent for spec-opaque payloads (e.g. smpte2038’s undecoded ST 291-1 checksum/parity): a raw &[u8] here is not a “raw-byte API” violation because there is no further spec structure to type.

Fields§

§profile_id: u16

defined by profile — a 16-bit identifier whose meaning is entirely profile-specific (§5.3.1).

§data: &'a [u8]

The extension data. Its on-the-wire length (in 32-bit words) is always derived from data.len() / 4 on serialize — never stored as an independent field that could disagree with the slice. data.len() MUST be a multiple of 4 (§5.3.1: length counts whole 32-bit words).

Implementations§

Source§

impl HeaderExtension<'_>

Source

pub fn length_words(&self) -> usize

The length field value that will be written on serialize: the number of 32-bit words in data (§5.3.1, “excluding the four-octet extension header”).
