Asynchronously attempts to retrieve an existing cache entry.

public System.Threading.Tasks.ValueTask<bool> TryGetAsync (string key, System.Buffers.IBufferWriter<byte> destination, System.Threading.CancellationToken token = default);

abstract member TryGetAsync : string * System.Buffers.IBufferWriter<byte> * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<bool>

Public Function TryGetAsync (key As String, destination As IBufferWriter(Of Byte), Optional token As CancellationToken = Nothing) As ValueTask(Of Boolean)

Parameters

key

String

The unique key for the cache entry.

destination

IBufferWriter<Byte>

The target to write the cache contents on success.

token

CancellationToken

The CancellationToken used to propagate notifications that the operation should be canceled.

Returns

ValueTask<Boolean>

true if the cache entry is found, false otherwise.

Remarks

This method is functionally similar to GetAsync(String, CancellationToken), but avoids the array allocation.
