2. public static ValueTask<bool> AllAsync<T>(this IObservableAsync<T> @this, Func<T, bool> predicate, CancellationToken cancellationToken)

1. Overload¶

public static ValueTask<bool> AllAsync<T>(this IObservableAsync<T> @this, Func<T, bool> predicate)

View source

Summary: Asynchronously determines whether all elements in the sequence satisfy the specified predicate.

Type parameters

Name	Description
`T`	The type of the elements in the source sequence.

Parameters

Name	Type	Description
`this`	[IObservableAsync](#	The source observable sequence.
`predicate`	Func	A function to test each element for a condition. The method evaluates this predicate for each element in the sequence.

Returns: ValueTask -- A task that represents the asynchronous operation. The task result contains true if every element of the sequence passes the test in the specified predicate, or if the sequence is empty; otherwise, false.

Exceptions

Type	Condition
System.ArgumentNullException	Thrown if `predicate` is `null`.

2. Overload¶

public static ValueTask<bool> AllAsync<T>(this IObservableAsync<T> @this, Func<T, bool> predicate, CancellationToken cancellationToken)
