Applies specified action to each collection element asynchronously.

public static ValueTask ForEachAsync<T>(this IAsyncEnumerable<T> collection, Func<T, CancellationToken, ValueTask> action, CancellationToken token = default)

Applies specified action to each collection element asynchronously.

public static ValueTask ForEachAsync<T>(this IEnumerable<T> collection, Func<T, CancellationToken, ValueTask> action, CancellationToken token = default)

Applies the specified asynchronous action to each collection element.

public static IAsyncEnumerator<T> GetAsyncEnumerator<T>(this IEnumerable<T> enumerable, CancellationToken token = default)
