Syntax

public struct CallOptions

Constructors

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

Creates a new instance of CallOptions struct.

Declaration

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

Parameters

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

Properties

CancellationToken

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.

Declaration

public CancellationToken CancellationToken { get; }

Property Value

Type	Description
System.Threading.CancellationToken

Credentials

Credentials to use for this call.

Declaration

public CallCredentials Credentials { get; }

Property Value

Type	Description
CallCredentials

Deadline

Call deadline.

Declaration

public DateTime? Deadline { get; }

Property Value

Type	Description
System.Nullable<System.DateTime>

Headers

Headers to send at the beginning of the call.

Declaration

public Metadata Headers { get; }

Property Value

Type	Description
Metadata

IsWaitForReady

If true and channel is in ChannelState.TransientFailure, the call will attempt waiting for the channel to recover instead of failing immediately (which is the default "FailFast" semantics). Note: experimental API that can change or be removed without any prior notice.

Declaration

public bool IsWaitForReady { get; }

Property Value

Type	Description
System.Boolean

PropagationToken

Token for propagating parent call context.

Declaration

public ContextPropagationToken PropagationToken { get; }

Property Value

Type	Description
ContextPropagationToken

WriteOptions

Write options that will be used for this call.

Declaration

public WriteOptions WriteOptions { get; }

Property Value

Type	Description
WriteOptions
