Queue.isEnqueue

Type guard to check if a value is an Enqueue.

When to use

Use to narrow an unknown value before calling queue operations that require write-side access.

Gotchas

A full Queue also satisfies this guard because every queue includes the enqueue side.

See

• isQueue for checking for a full read-write queue handle
• isDequeue for checking for the read side of a queue
• asEnqueue for narrowing an existing Queue to its write-only interface

Signature

declare const isEnqueue: <A = unknown, E = unknown>(u: unknown) => u is Enqueue<A, E>
