Provides a set of extension methods for IAsyncEnumerator<T>.
public static IAsyncEnumerator<T> Create<T>(Func<ValueTask<bool>> moveNextAsync, Func<T> getCurrent, Func<ValueTask> disposeAsync)

Creates a new enumerator using the specified delegates implementing the members of IAsyncEnumerator<T>.

public static ValueTask<bool> MoveNextAsync<T>(this IAsyncEnumerator<T> source, CancellationToken cancellationToken)

Advances the enumerator to the next element in the sequence, returning the result asynchronously.

public static IAsyncEnumerator<T> WithCancellation<T>(this IAsyncEnumerator<T> source, CancellationToken cancellationToken)

Wraps the specified enumerator with an enumerator that checks for cancellation upon every invocation of the MoveNextAsync method.
