Struct StateMap 

pub struct StateMap { /* private fields */ }

Maps 256 states to adaptive 12-bit probabilities.

Implementations

impl StateMap

pub fn new() -> Self

Create a new StateMap initialized from the StateTable’s static probabilities.

pub fn predict(&self, state: u8) -> u32

Get the predicted probability of bit=1 for the given state. Returns a 12-bit value in [1, 4095].

pub fn update(&mut self, state: u8, bit: u8)

Update the probability for the given state after observing bit. Uses adaptive learning: p += (target - p) / (count + MIN_DENOM). Learning rate decreases as count increases (1/n convergence).

Trait Implementations

impl Default for StateMap

fn default() -> Self

Returns the “default value” for a type.
