pub struct VideoRate { /* private fields */ }

Implementations

impl VideoRate

pub fn camera(cap: usize) -> Self

pub fn screen(cap: usize) -> Self

pub fn new( ladder: &'static [Rung], camera: bool, start: usize, cap: usize, ) -> Self

pub fn rung(&self) -> Rung

pub fn rungs(&self) -> usize

pub fn set_pin(&mut self, pin: Option<usize>) -> Option<Rung>

Hold a rung, or let the ladder run again. A held rung may sit above the path’s cap: the cap is a default for the ladder, the pin is the user’s word. Returns the rung when it moved.

pub fn set_fps(&mut self, fps: Option<u32>) -> Rung

pub fn is_camera(&self) -> bool

pub fn set_cap(&mut self, cap: usize) -> Option<Rung>

A new ceiling (the path changed, or the peer said how much it can take). Returns the rung when the ceiling pushed it down. The round-trip floor starts over too: a new path has its own.

pub fn observe(&mut self, obs: VideoObservation) -> Option<Rung>

Once a second. Returns the rung to switch to when it changed.
