Struct BitwiseClause 

pub struct BitwiseClause { /* private fields */ }

Overview

Bitwise clause using packed u64 bitmasks.

Processes 64 features per AND operation - up to 50x faster than scalar.

Implementations

impl BitwiseClause

pub fn new(n_features: usize, n_states: i16, polarity: i8) -> Self

Overview

Creates clause with given features, states, and polarity.

pub const fn polarity(&self) -> i8

pub const fn n_features(&self) -> usize

pub fn automata(&self) -> &[Automaton]

pub fn automata_mut(&mut self) -> &mut [Automaton]

pub fn rebuild_masks(&mut self)

Overview

Rebuilds bitmasks from automaton states. Call after training.

pub fn evaluate_packed(&self, x_packed: &[u64]) -> bool

Evaluates clause using bitwise AND operations.

Processes 64 features per CPU instruction for massive speedup.

Arguments

• x_packed - Input packed as u64 words via pack_input

Panics

Debug-asserts that rebuild_masks() was called after training.

pub fn vote_packed(&self, x_packed: &[u64]) -> i32

Returns polarity if fires, 0 otherwise.

pub fn evaluate(&self, x: &[u8]) -> bool

Fallback scalar evaluation (no packing needed).

Slower than evaluate_packed but works with unpacked input.

Trait Implementations

impl Clone for BitwiseClause

fn clone(&self) -> BitwiseClause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BitwiseClause

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

Formats the value using the given formatter.
