Struct CallOptions (2.48.0)

public struct CallOptions

Options for calls made by client.

Namespace

Grpc.Core

Assembly

Grpc.Core.Api.dll

Constructors

CallOptions(Metadata, Nullable<DateTime>, CancellationToken, WriteOptions, ContextPropagationToken, CallCredentials)

public CallOptions(Metadata headers = null, DateTime? deadline = null, CancellationToken cancellationToken = null, WriteOptions writeOptions = null, ContextPropagationToken propagationToken = null, CallCredentials credentials = null)

Creates a new instance of CallOptions struct.

Parameters

Name	Description
headers	Metadata Headers to be sent with the call.
deadline	Nullable<DateTime> Deadline for the call to finish. null means no deadline.
cancellationToken	CancellationToken Can be used to request cancellation of the call.
writeOptions	WriteOptions Write options that will be used for this call.
propagationToken	ContextPropagationToken Context propagation token obtained from ServerCallContext.
credentials	CallCredentials Credentials to use for this call.

Properties

CancellationToken

public readonly CancellationToken CancellationToken { get; }

Token that can be used for cancelling the call on the client side. Cancelling the token will request cancellation of the remote call. Best effort will be made to deliver the cancellation notification to the server and interaction of the call with the server side will be terminated. Unless the call finishes before the cancellation could happen (there is an inherent race), the call will finish with StatusCode.Cancelled status.

Property Value

CancellationToken

Credentials

public readonly CallCredentials Credentials { get; }

Credentials to use for this call.

Property Value

Headers

IsWaitForReady

public readonly bool IsWaitForReady { get; }
