Struct ScyllaDeque<T>.Enumerator

Value-type forward enumerator for ScyllaDeque<T> that allows allocation-free foreach iteration over the concrete deque type.

Syntax

public struct ScyllaDeque<T>.Enumerator

Remarks

The enumerator snapshots Count and _head at construction time and uses them throughout iteration. Modifying the deque (pushing, popping, or clearing) while an enumerator is active produces undefined results; no exception is thrown. Iteration order is always front-to-back, wrapping around the end of the circular buffer as needed.

Constructors

Enumerator(ScyllaDeque<T>)

Initializes a new ScyllaDeque<T>.Enumerator positioned before the first element of deque.

Declaration

public Enumerator(ScyllaDeque<T> deque)

Parameters

Type	Name	Description
ScyllaDeque<T>	deque	The deque to enumerate. Must not be null.

Properties

Current

Gets the element at the current enumerator position. The value is default(T) before the first call to MoveNext() and after the enumerator has passed the last element.

Declaration

public readonly T Current { get; }

Property Value

Type	Description
T

Methods

MoveNext()

Advances the enumerator to the next element in front-to-back order.

Declaration

public bool MoveNext()

Returns

Type	Description
bool	true if the enumerator was successfully advanced to the next element; false if the enumerator has passed the end of the snapshot.

Remarks

The circular-buffer index is computed as (_start + _index) % buffer.Length, using the snapshot of _head captured at construction rather than the live _head, so iteration is stable against front-pops during enumeration (though such modifications are still discouraged).
