Struct GateFilter 

pub struct GateFilter { /* private fields */ }

Which gates a rule fires after.

An unset field imposes no restriction, so GateFilter::all matches every gate on every qubit.

Implementations

impl GateFilter

pub fn all() -> Self

pub fn arity(self, arity: usize) -> Self

Restrict to gates with exactly arity targets.

pub fn named(self, name: impl Into<String>) -> Self

Restrict to gates whose Gate::name equals name, such as "cx".

A name no gate in the circuit carries is not an error: the rule emits nothing. Fusion renames gates ("fused", "fused_2q", "multi_fused"), so build the model against the circuit the caller holds rather than a fused stream.

pub fn on_qubits(self, qubits: impl IntoIterator<Item = usize>) -> Self

Restrict to the listed qubits, as an unordered set. Every rule kind honours it: one acting per target emits events only on the targets in the set, and one acting on a gate’s whole target list, or on the spectators of a target, fires only for targets the set admits.

pub fn on_targets(self, targets: impl IntoIterator<Item = usize>) -> Self

Restrict to gates whose target list equals targets in order.

Directed, unlike GateFilter::on_qubits: on_targets([0, 1]) matches cx(0, 1) and not cx(1, 0), which is what a calibration table keyed by coupling-map edge needs.
