| TakeWhile<TSource>(IAsyncEnumerable<TSource>, Func<TSource,Boolean>) |
Returns elements from a sequence as long as a specified condition is true. |
| TakeWhile<TSource>(IAsyncEnumerable<TSource>, Func<TSource,Int32,Boolean>) |
Returns elements from a sequence as long as a specified condition is true. The element's index is used in the logic of the predicate function. |
| TakeWhile<TSource>(IAsyncEnumerable<TSource>, Func<TSource,Int32,CancellationToken,ValueTask<Boolean>>) |
Returns elements from a sequence as long as a specified condition is true. The element's index is used in the logic of the predicate function. |
