Struct And

Source

pub struct And<A, B>(pub A, pub B);

Expand description

Logical AND of two policies — both must accept.

§Examples

use paulistrings::truncation::{And, CoefficientThreshold, WeightCutoff};
let policy = And(CoefficientThreshold(1e-6), WeightCutoff(4));

Tuple Fields§

§0: A

First policy. keep_term and finalize_layer both consult this first.

§1: B

Second policy.

Trait Implementations§

Source §

impl<const W: usize, A, B> TruncationPolicy<W> for And<A, B>
where A: TruncationPolicy<W>, B: TruncationPolicy<W>,

Source §

fn keep_term(&self, x: &[u64; W], z: &[u64; W], c: Complex64) -> bool

Cheap per-term filter applied during the merge phase. Must inline. Read more

Source §

fn finalize_layer(&self, sum: &mut PauliSum<W>)

Optional global pass after each circuit layer. May be non-local (e.g. partial sort for TopN).

Auto Trait Implementations§

§

impl<A, B> Freeze for And<A, B>
where A: Freeze, B: Freeze,

§

impl<A, B> RefUnwindSafe for And<A, B>
where A: RefUnwindSafe, B: RefUnwindSafe,

§

impl<A, B> UnwindSafe for And<A, B>
where A: UnwindSafe, B: UnwindSafe,
