Struct ScratchPerformance 

pub struct ScratchPerformance { /* private fields */ }

Canonical allocation-free scratch helper for physical player consumers.

Implementations

impl ScratchPerformance

pub fn new(preset: ScratchPreset) -> Self

pub const fn catalog() -> &'static [ScratchPresetDescriptor; 8]

pub fn preset(&self) -> ScratchPreset

pub fn set_preset(&mut self, preset: ScratchPreset)

pub fn clicks(&self) -> u8

pub fn set_clicks(&mut self, clicks: u8)

pub fn audible_gain(&self) -> f64

pub fn gate(&self) -> &ScratchGate

pub fn output(&self) -> ScratchPerformanceOutput

Reports the current output state without advancing the helper.

pub fn process_frame( &mut self, input: ScratchPerformanceInput, ) -> Result<ScratchPerformanceOutput, ScratchPerformanceError>

Processes one frame after the physical mechanics step for that frame.

pub fn snapshot(&self) -> ScratchPerformanceSnapshot

pub fn restore( &mut self, snapshot: &ScratchPerformanceSnapshot, ) -> Result<(), ScratchPerformanceError>

Restores only after the complete snapshot passes validation.
