Struct ReplayEngine 

pub struct ReplayEngine { /* private fields */ }

Engine that records execution parameters and replays simulations for reproducibility verification.

Implementations

impl ReplayEngine

pub fn new() -> Self

Create a new ReplayEngine using the crate version from Cargo.toml.

pub fn record_execution( &self, circuit: &QuantumCircuit, config: &SimConfig, shots: u32, ) -> ExecutionRecord

Capture all parameters needed to deterministically replay a simulation.

The returned ExecutionRecord is self-contained: given the same circuit, the record holds enough information to reproduce the exact measurement outcomes.

pub fn replay(&self, record: &ExecutionRecord, circuit: &QuantumCircuit) -> bool

Replay a simulation using the parameters in record and verify that the measurement outcomes match a fresh run.

Returns true when the replayed results are identical to a reference run seeded with the same parameters. Both runs use the exact same seed so the RNG sequences must agree.

pub fn circuit_hash(circuit: &QuantumCircuit) -> [u8; 32]

Compute a deterministic 32-byte hash of a circuit’s structure.

The hash captures, for every gate: its type discriminant, the qubit indices it acts on, and any continuous parameters (rotation angles). Two circuits with the same gate sequence produce the same hash.

Uses DefaultHasher (SipHash-based) run twice with different seeds to fill 32 bytes.

Trait Implementations

impl Default for ReplayEngine

fn default() -> Self

Returns the “default value” for a type.
