Struct StabilityMask 

pub struct StabilityMask { /* private fields */ }

Temporal stability mask: keeps only blocks that are stable over recent ticks yet novel versus a longer-term baseline — isolating newly-appeared static overlays (tooltips) from moving gameplay and permanent HUD. Suppressed blocks render black; kept blocks pass through byte-identical. See the design spec for the algebra.

Implementations

impl StabilityMask

pub fn new() -> Self

pub fn block_size(self, px: u32) -> Self

Analysis block size in pixels (default 16).

pub fn stable_ticks(self, k: u32) -> Self

Consecutive stable ticks before a block counts as stable (default 6).

pub fn stable_for(self, rate: Rate, duration: Duration) -> Self

Duration form of Self::stable_ticks; converted via the watcher’s rate (tick-based internals keep paused-time tests deterministic).

pub fn baseline_ticks(self, t: u32) -> Self

Baseline EMA horizon in ticks (default 100).

pub fn baseline(self, rate: Rate, duration: Duration) -> Self

Duration form of Self::baseline_ticks.

pub fn dilate(self, rings: u32) -> Self

Keep-mask dilation rings (default 1) — keeps glyphs off the fill boundary and closes holes inside kept clusters.

pub fn signature_tolerance(self, tol: u8) -> Self

Stability comparison tolerance on the 0-255 luma signature (default 4).

pub fn baseline_threshold(self, thr: u8) -> Self

Novelty threshold versus the baseline (default 25).

pub fn debug_sink(self, sink: impl DebugSink) -> Self

Attach a debug tap (e.g. PngDump) receiving per-tick Input/Baseline/Overlay/Output frames. Composable — multiple sinks allowed. Stage frames are only materialized when at least one sink is attached.

Trait Implementations

impl Default for StabilityMask

fn default() -> Self

Returns the “default value” for a type.

impl Preprocessor for StabilityMask

fn process(&mut self, view: &FrameView<'_>) -> Result<Arc<Frame>, DetectorError>

fn set_label(&mut self, label: &str)

Called once at subscribe time with the watcher’s name, so stages with debug output can label their artifacts. Default: ignore.
