Struct SmallBitwiseClause 

pub struct SmallBitwiseClause<const N: usize, const W: usize> { /* private fields */ }

Bitwise clause with compile-time known feature count.

Uses packed u64 bitmasks for SIMD-friendly evaluation. Processes 64 features per AND operation.

Type Parameters

• N - Number of features (compile-time constant)
• W - Number of u64 words needed: (N + 63) / 64

Implementations

impl<const N: usize, const W: usize> SmallBitwiseClause<N, W>

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

Creates bitwise clause with given states and polarity.

Panics

Debug-asserts that W == (N + 63) / 64.

pub const fn polarity(&self) -> i8

Returns the clause polarity (+1 or -1).

pub const fn n_features(&self) -> usize

Returns the number of features (compile-time constant).

pub const fn include_automata(&self) -> &[Automaton; N]

Returns read-only access to include automata.

pub fn include_automata_mut(&mut self) -> &mut [Automaton; N]

Returns mutable access to include automata.

pub const fn negated_automata(&self) -> &[Automaton; N]

Returns read-only access to negated automata.

pub fn negated_automata_mut(&mut self) -> &mut [Automaton; N]

Returns mutable access to negated automata.

pub fn rebuild_masks(&mut self)

Rebuilds bitmasks from automaton states.

Call after training before evaluation.

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

Evaluates clause using bitwise AND operations.

Processes 64 features per CPU instruction for massive speedup.

Panics

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

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

Returns polarity if fires, 0 otherwise.

pub fn vote_weighted_packed(&self, x_packed: &[u64; W]) -> f32

Returns weighted vote if fires.

Trait Implementations

impl<const N: usize, const W: usize> Clone for SmallBitwiseClause<N, W>

fn clone(&self) -> SmallBitwiseClause<N, W>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const N: usize, const W: usize> Debug for SmallBitwiseClause<N, W>

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