Enum Recovery 

pub enum Recovery {
    Ltr,
    IntraRefresh,
    Idr,
}

What the publisher is asked to produce to make the stream decodable again, cheapest first.

Seyd states intent and the robot-side publisher decides how to meet it: a publisher that cannot honour Ltr is free to send an IDR instead, and one that ignores kind entirely behaves exactly as before. Asking for the cheapest rung matters because an IDR is a bandwidth spike — measured at 30-60 KB against a ~2 KB delta — and on a ~2 Mbps uplink that spike is 120-240 ms of serialisation, which is what field run A recorded as p95.

Variants

Ltr

Re-encode one frame against a long-term reference the pilot still has. Cheapest: a single ordinary-sized frame restores decodability.

IntraRefresh

Refresh the picture progressively across many frames. No single frame is large, so the bitrate stays flat, but decodability returns gradually.

Idr

A full keyframe. The only rung that lets a decoder start from nothing, and the only one a pilot’s request-keyframe can be answered with.

Trait Implementations

impl Clone for Recovery

fn clone(&self) -> Recovery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Recovery

impl Debug for Recovery

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

Formats the value using the given formatter.

impl Eq for Recovery

impl PartialEq for Recovery

fn eq(&self, other: &Recovery) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
