Struct MeasRegistry 

pub struct MeasRegistry { /* private fields */ }

Allocator and lookup table for a circuit’s measurement ids.

Records are kept strictly sorted by id. Dense ids use direct indexing; sparse lookups fall back to binary search. On the wire only the records are stored; the next-id counter is recomputed on decode (see the serde impls) rather than trusted.

Implementations

impl MeasRegistry

pub fn new() -> Self

Creates an empty measurement registry.

pub fn allocate(&mut self, qubits: impl IntoIterator<Item = IVec2>) -> Vec<u32>

Allocates one sequential id per qubit, appending a record for each, and returns the ids in input order.

pub fn allocate_one(&mut self, qubit: IVec2) -> u32

Allocates a single sequential id for qubit, appending its record — the Self::allocate core without the return Vec, for hot callers that allocate one id at a time.

Panics

Panics if the measurement-id space is exhausted.

pub fn reserve(&mut self, id: u32, qubit: IVec2)

Reserve id for qubit, keeping the record list sorted. Reserving an already-reserved id for the same qubit is a no-op.

Panics

Panics if id is already reserved for a different qubit or is u32::MAX. The registry is unchanged if this check fails.

pub fn record(&self, id: u32) -> Option<&MeasRecord>

Borrows the record for id, or None if it is not allocated.

pub fn records(&self) -> &[MeasRecord]

All records, sorted by id.
