Struct AdaptiveFrequencyTracker 

pub struct AdaptiveFrequencyTracker { /* private fields */ }

Adaptive frequency tracker using a sliding window.

Maintains a ring buffer of recent symbols and computes up-to-date frequency counts for probability estimation.

Implementations

impl AdaptiveFrequencyTracker

pub fn new(window_size: usize) -> Self

Create a tracker with the given window size.

pub fn observe(&mut self, symbol: u8)

Add a new symbol observation.

pub fn frequency(&self, symbol: u8) -> u32

Get the current frequency of symbol.

pub fn total(&self) -> usize

Get the total number of observations in the window.

pub fn probability(&self, symbol: u8) -> f64

Get the estimated probability of symbol (0.0 if no observations).

pub fn frequency_table(&self) -> [u32; 256]

Return the full 256-entry frequency table (snapshot).

pub fn reset(&mut self)

Reset the tracker to its initial state.
