Struct MediaRequestIdentity 

pub struct MediaRequestIdentity { /* private fields */ }

Pending identity used to decide whether a handset media ACK belongs to the currently opening receive/transmit request.

Implementations

impl MediaRequestIdentity

pub const fn new(generation: u64, token: MediaRequestToken) -> Option<Self>

Construct an identity. Generations are monotonic per call and start at one; a deliberately coupled ORC/SMT pair shares one identity. Tokens must be allocated uniquely among live and retired media sessions.

pub const fn generation(self) -> u64

pub const fn token(self) -> MediaRequestToken

pub const fn checked_next(self) -> Option<Self>

Advance both the logical generation and its wire token without wrap. A caller must fail the media reopen when this returns None.

pub const fn accepts_ack( self, acknowledgement_party_id: u32, acknowledgement_call_reference: u32, stable_call_reference: u32, ) -> bool

Match an ACK without permitting a prior generation to settle a reopen.

An SMT acknowledgement may omit the party ID. That fallback is safe only for generation one and only with the stable call reference; after a reopen, a zero-party ACK is intrinsically ambiguous and fails closed. A present party ID must match the fresh token, while a present call reference must still identify the same call.
