Struct GatePattern 

pub struct GatePattern {
    pub gate: GateSpec,
    pub params: Vec<Parameter>,
    pub qubits: Vec<u32>,
}

Surface AST for a single gate pattern.

A pattern looks like RZ(a + b) 0 or MCX[3] 0 1 2 3:

• gate = gate identifier
• params = [Parameter("a + b")]
• qubits = [0]

Fields

gate: GateSpec

Gate identifier.

params: Vec<Parameter>

Parameter expressions appearing inside the parentheses.

qubits: Vec<u32>

Qubit indices appearing after the parentheses.

Implementations

impl GatePattern

pub fn into_pattern_op(self) -> Result<RuleItem, LowerError>

Lowers this surface pattern into a runtime match RuleItem.

The lowering process:

1. Resolves the pattern gate to a standard gate or an MCGate.
2. Validates that qubits.len() equals the gate’s expected qubit count.
3. Validates that params.len() equals the gate’s expected parameter count.
4. Attempts to evaluate each parameter to a constant; if that fails, the parameter is kept as a symbolic ParameterValue::Param.

pub fn into_build_op(self) -> Result<RuleItem, LowerError>

Lowers this surface pattern into a runtime rewrite RuleItem.

The lowering process is identical to into_pattern_op except it is used for rewrite block diagnostics and validation.
