}

Data contract for the Diff Strategy cockpit panel.

Source of truth: ftui::runtime::evidence_telemetry::diff_snapshot()

Answers: “Why did the last frame use full vs partial redraw?”

Fields

last_was_full_redraw: bool

Whether the last frame was a full redraw.

dirty_row_count: u32

Number of dirty rows detected in the last partial redraw.

total_row_count: u32

Total row count for the frame (dirty_row_count / total = dirty ratio).

reason: &'static str

Reason for the diff decision (human-readable).

consecutive_full_redraws: u32

Number of consecutive full redraws.

full_redraw_ratio: f64

Cumulative full-redraw ratio (full / total frames observed).

Implementations

impl DiffStrategyContract

pub fn dirty_ratio(&self) -> f64

Dirty row ratio (0.0..1.0). Returns 0.0 if total_row_count is zero.

pub fn has_data(&self) -> bool

Whether meaningful data has been captured.

Trait Implementations

impl Clone for DiffStrategyContract

fn clone(&self) -> DiffStrategyContract

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiffStrategyContract

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

Formats the value using the given formatter.

impl Default for DiffStrategyContract

fn default() -> DiffStrategyContract

Returns the “default value” for a type.
