Struct Screencast 

pub struct Screencast { /* private fields */ }

Shared screencast state. Thread-safe; mutex locks are short-lived and recover from poisoning.

Implementations

impl Screencast

pub fn start( &self, interval_ms: u64, max_frames: usize, label: Option<String>, ) -> u64

Begin a new trace: clears frames, records settings, returns the generation token the capture task must check to know it is current.

pub fn stop(&self) -> usize

Stop the current trace. Returns the captured frame count.

pub fn is_active(&self) -> bool

Whether a trace is currently active.

pub fn generation(&self) -> u64

The current generation token (a capture task is stale if it differs).

pub fn interval_ms(&self) -> u64

Configured capture interval in milliseconds.

pub fn label(&self) -> Option<String>

Target webview label for capture, if set.

pub fn push_frame(&self, t_ms: u64, data_b64: String)

Append a frame, enforcing the max_frames ring-buffer cap.

pub fn frame_count(&self) -> usize

Number of frames currently buffered.

pub fn frames(&self, limit: usize) -> Vec<TraceFrame>

Return up to limit of the most recent frames (or all if limit is 0).

pub fn frame_timestamps(&self) -> Vec<u64>

Frame timestamps (ms since start) without the image payloads.

Trait Implementations

impl Debug for Screencast

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

Formats the value using the given formatter.

impl Default for Screencast

fn default() -> Self

Returns the “default value” for a type.
