AsyncDirectoryIterator
Owns consuming directory traversal and transfers independent entry owners. Successful EOF is sticky. Native step failures end traversal; pre-step cancellation/admission failures permit retry. External synchronization is required; destruction closes remaining enumeration synchronously. No raw native entry or borrowed name escapes.

AsyncDirectoryIterator.init
pub init()Creates an inert allocation-free cursor.
AsyncDirectoryIterator.init
pub init(Source: readonly Self&) = delete;Rejects duplicated traversal authority. Source: Existing cursor.
AsyncDirectoryIterator.init
pub init(Source: mut Self&&)Transfers remaining enumeration and terminal state. Source: Cursor left exhausted.
AsyncDirectoryIterator.operator
pub fn operator =(Source: readonly Self&) -> void = delete;Rejects duplicated enumeration authority. Source: Existing cursor. Return: No runtime result; this assignment is deleted and cannot be invoked.
AsyncDirectoryIterator.operator
pub fn operator =(Source: mut Self&&) -> void = delete;Requires explicit owner cleanup before replacement. Source: Existing cursor. Return: No runtime result; this assignment is deleted and cannot be invoked.
AsyncDirectoryIterator.NextAsync
pub async fn NextAsync(mut Token: CancellationToken) -> Task<Result<DirectoryEntry?, IoError>>Reads one owned entry, preserving cancellation/admission retryability. Token: Cancellation observation for this step only. Return: Task yielding owned optional entry or exact source-specific error. Warning: One mutable step at a time; cursor must remain live while pending.
AsyncDirectoryIterator.NextAsync
pub fn NextAsync() -> Task<Result<DirectoryEntry?, IoError>>Supplies the omitted arguments to NextAsync. Note: Defaults: Token = CancellationToken(). Return: Exact full-operation result; no additional async frame is created.
