Struct IncrementalMODWTState 

pub struct IncrementalMODWTState {
    pub level_states: Vec<IncrementalLevelState>,
    pub filters: IncrementalMODWTFilters,
    pub latest_wavelets: Vec<f64>,
    pub latest_scaling: f64,
    pub tick_count: u64,
}

Incremental MODWT state for O(L) per-tick updates

This structure maintains the pyramid algorithm state, allowing computation of only the new coefficients when a tick arrives.

Uses f64 internally for SIMD compatibility and numerical precision.

Fields

level_states: Vec<IncrementalLevelState>

Per-level state buffers

filters: IncrementalMODWTFilters

Pre-computed filters

latest_wavelets: Vec<f64>

Most recent wavelet coefficients (one per level)

latest_scaling: f64

Most recent scaling coefficient (from deepest level)

tick_count: u64

Total ticks processed

Implementations

impl IncrementalMODWTState

pub fn new(wavelet: &dyn Wavelet, levels: usize) -> Self

Create new incremental state

pub fn update(&mut self, sample: f64) -> bool

Process a single new sample through the pyramid

This is the core O(L × filter_len) algorithm that replaces the O(N × L × filter_len) batch recomputation.

Zero-allocation in the hot path.

pub fn clear(&mut self)

Clear all state

pub fn is_ready(&self) -> bool

Check if state has enough data for all levels

Trait Implementations

impl Clone for IncrementalMODWTState

fn clone(&self) -> IncrementalMODWTState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IncrementalMODWTState

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

Formats the value using the given formatter.
