Struct KeyframeGate 

pub struct KeyframeGate { /* private fields */ }

Available on crate feature ingest only.

Gate that suppresses delta frames until the first IDR (keyframe) arrives, so late-joining or re-subscribing clients always start at a clean decoder boundary.

use arcly_stream::protocol::KeyframeGate;
use arcly_stream::FrameType;

let mut gate = KeyframeGate::new();
// A delta frame before any keyframe is held back:
assert!(!gate.admit(FrameType::Delta));
// The first keyframe opens the gate and is itself admitted:
assert!(gate.admit(FrameType::Key));
// Subsequent deltas now flow:
assert!(gate.admit(FrameType::Delta));
// Audio always flows (it carries no decode dependency on video IDRs):
assert!(KeyframeGate::new().admit(FrameType::Audio));

Implementations

impl KeyframeGate

pub fn new() -> Self

Create a new gate (initially closed — non-audio frames are held).

pub fn open(&mut self)

Open the gate unconditionally.

pub fn is_open(&self) -> bool

Whether the gate is currently open.

pub fn admit(&mut self, frame_type: FrameType) -> bool

Decide whether a frame of the given type should be admitted, opening the gate on the first keyframe. Audio is always admitted.

Trait Implementations

impl Debug for KeyframeGate

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

Formats the value using the given formatter.

impl Default for KeyframeGate

fn default() -> KeyframeGate

Returns the “default value” for a type.
