Struct Config 

#[non_exhaustive]
pub struct Config {
    pub hop: Hop,
    pub pool: Pool,
    pub cache_duration: Duration,
    pub default_max_age: Duration,
}

An origin’s identity plus the cache pool its broadcasts inherit.

Construction config for an origin Producer. The origin passes its cache::Pool to every broadcast it creates, so every track and group beneath it shares one budget. Defaults to no byte target and the cache’s standard idle expiry.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

hop: Hop

The origin’s wire identity, appended to broadcast hop chains for loop detection and shortest-path routing.

pool: Pool

The cache pool broadcasts under this origin charge their groups into. It flows down the ownership chain (origin -> broadcast -> track -> group): a track opens an account against it, and its groups charge through that. It has no byte target and uses cache::DEFAULT_EXPIRY by default; a relay sets a shared configured pool (assign Self::pool) so cached groups across the whole process share one policy.

cache_duration: Duration

Ceiling on each track’s media-timestamp retention window under this origin. Each track’s own max_age is clamped down to this when the track binds, so a subscriber is never promised more history than the origin allows, regardless of what a publisher advertises. Wall-clock reclamation of idle content is separate: Self::pool’s expiry window. Duration::MAX (the default) imposes no ceiling, leaving each track’s own window in force.

default_max_age: Duration

The retention window given to a track whose publisher advertises none.

moq-lite 05+ carries max_age in TRACK_INFO, so a track relayed over it keeps the window its publisher chose. Every moq-transport draft and moq-lite 01-04 have no such wire property, so a track arriving over one of them lands here instead. Raise it on a relay fronting a segmented egress (HLS/DASH), which needs a playlist window’s worth of history rather than the live edge. Defaults to track::DEFAULT_MAX_AGE, and Self::cache_duration still caps it.
