Struct MockQuantumBackend 

pub struct MockQuantumBackend {
    pub config: MockBackendConfig,
    /* private fields */
}

A configurable mock quantum backend for use in integration tests.

All submitted jobs are recorded and can be retrieved via MockQuantumBackend::all_jobs. Measurement results are generated deterministically from the configured seed so that tests are reproducible.

Fields

config: MockBackendConfig

Public backend configuration

Implementations

impl MockQuantumBackend

pub fn new(config: MockBackendConfig) -> Self

Create a new mock backend with the given configuration.

pub fn job_count(&self) -> usize

Return the number of jobs submitted so far.

pub fn all_jobs(&self) -> Vec<MockJobRecord>

Return a snapshot of all job records accumulated so far.

pub fn last_job(&self) -> Option<MockJobRecord>

Return the most recently submitted job, or None if no jobs have run.

pub fn run( &self, circuit_qasm: &str, shots: usize, ) -> Result<HashMap<String, usize>, MockBackendError>

Submit a QASM 2.0 circuit and return measurement counts.

Validates qubit and shot limits, optionally simulates latency, optionally injects a simulated failure, then generates and returns measurement counts. Every invocation appends a MockJobRecord to the backend’s log.

pub fn capabilities(&self) -> HashMap<String, String>

Return a map of backend capabilities (suitable for display / comparison).

pub fn supports_gate(&self, gate_name: &str) -> bool

Return true when the given gate name is supported by this backend.

An empty gate set (the default) means every gate is accepted.

pub fn is_connected(&self, q0: usize, q1: usize) -> bool

Return true when the pair (q0, q1) is a valid 2-qubit connection.

An empty connectivity list (the default) means all pairs are allowed.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
