Struct Info 

#[non_exhaustive]
pub struct Info {
    pub id: Origin,
    pub pool: Pool,
}

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

Doubles as the construction config for an origin Producer and as the parent handle every broadcast carries (broadcast::Info::origin): the origin owns the cache::Pool every group in the tree registers with, so a relay configures one bounded pool here and every broadcast, track, and group beneath it reaches that single budget by walking up the ownership chain. Defaults to an unbounded pool (Origin::produce is the shorthand for that). Cheap to clone (a Copy id plus an Arc-handle bump), so it’s stored by value rather than behind another Arc.

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.

id: Origin

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 register their groups with. It flows down the ownership chain (origin -> broadcast -> track -> group), so a group reaches it via track.broadcast.origin.pool. Unbounded by default; a relay sets a bounded one (via Self::with_pool) so cached groups across the whole process share one memory budget.

Implementations

impl Info

pub fn new(id: Origin) -> Self

Config for the given origin id with an unbounded cache pool.

pub fn with_pool(self, pool: Pool) -> Self

Set the cache pool this origin’s broadcasts inherit, returning self for chaining.

pub fn produce(self) -> Producer

Consume this config to create an origin Producer.

Trait Implementations

impl Clone for Info

fn clone(&self) -> Info

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Info

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Info

fn default() -> Self

An unknown origin (id 0, no loop detection) with an unbounded pool. This is what a standalone broadcast (no relay origin) inherits.
