Struct AppSpec 

pub struct AppSpec {
    pub name: AppName,
    pub broadcast_capacity: usize,
    pub gop_capacity: usize,
}

Plain-Rust application descriptor — a named namespace of streams with its own fan-out capacity and GOP-replay policy. Build one fluently and register it via EngineBuilder::application.

use arcly_stream::prelude::*;

let live = AppSpec::new("live")
    .gop_cache(120)          // ~4s at 30fps → instant-start replay
    .broadcast_capacity(8192); // deeper buffer for very slow joiners

let engine = Engine::builder().application(live).build();
assert_eq!(engine.list_apps()[0].as_str(), "live");

Fields

name: AppName

Application name (e.g. "live").

broadcast_capacity: usize

Per-stream broadcast channel capacity (frames buffered for slow joiners).

gop_capacity: usize

Keyframe-anchored GOP replay buffer size, in frames (0 disables it). Enables sub-second playback start for late joiners.

Implementations

impl AppSpec

pub fn new(name: impl Into<AppName>) -> Self

A new app with default capacities and GOP caching disabled.

pub fn broadcast_capacity(self, n: usize) -> Self

Override the per-stream broadcast channel capacity.

pub fn gop_cache(self, frames: usize) -> Self

Enable the keyframe-anchored GOP replay buffer, bounded to frames (e.g. fps × gop_seconds). Late joiners receive the cached configs plus the current GOP and start decoding immediately.

Trait Implementations

impl Clone for AppSpec

fn clone(&self) -> AppSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppSpec

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

Formats the value using the given formatter.
