TargetBasisCostModel

cqlib_core::compile::transform::target_basis

Struct TargetBasisCostModel 

Source 
pub struct TargetBasisCostModel { /* private fields */ }
Expand description

Reusable, exact target-basis cost evaluator.

The evaluator shares the same lowerer and plans used by TargetBasisLowerer. It therefore measures the concrete output of the active rule library rather than maintaining a separate heuristic approximation for synthesis choices.

Implementations§

Source§

impl TargetBasisCostModel

Source

pub fn new(target_basis: Vec<Instruction>) -> Result<Self, CompilerError>

Builds an exact cost model for a non-empty standard-gate target basis.

Source

pub fn from_lowerer( lowerer: Arc<TargetBasisLowerer>, ) -> Result<Self, CompilerError>

Builds an exact cost model from an existing target-basis lowerer.

Source

pub const fn signature(&self) -> &TargetBasisSignature

Returns the canonical target identity used by synthesis caches.

Source

pub fn target_basis(&self) -> &[Instruction]

Returns the configured target instruction basis in insertion order.

Source

pub fn cost_of_fixed_operations( &self, qubits: Vec<Qubit>, operations: Vec<ValueOperation>, ) -> Result<TargetBasisCost, CompilerError>

Lowers fixed standard-gate operations and returns the exact resulting target-basis cost.

The supplied operations must reference only qubits, carry fixed finite parameters, and contain no classical control. These constraints match the numeric two-qubit synthesis and resynthesis callers.
