If channel is in ChannelState.TransientFailure, attempt waiting for the channel to recover instead of failing the call immediately. The call is cacheable. gRPC is free to use GET verb */ Abstraction of client-side RPC invocation. Invokes a simple remote call in a blocking fashion. Invokes a simple remote call asynchronously. Invokes a server streaming call asynchronously. In server streaming scenario, client sends on request and server responds with a stream of responses. Invokes a client streaming call asynchronously. In client streaming scenario, client sends a stream of requests and server responds with a single response. Invokes a duplex streaming call asynchronously. In duplex streaming scenario, client sends a stream of requests and server responds with a stream of responses. The response stream is completely independent and both side can be sending messages at the same time. Options for calls made by client. Creates a new instance of CallOptions struct. Headers to be sent with the call. Deadline for the call to finish. null means no deadline. Can be used to request cancellation of the call. Write options that will be used for this call. Context propagation token obtained from . Credentials to use for this call. Headers to send at the beginning of the call. Call deadline. 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. Write options that will be used for this call. Token for propagating parent call context. Credentials to use for this call. If true and 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. Flags to use for this call. Returns new instance of with Headers set to the value provided.

Returns new instance of with "WaitForReady" semantics enabled/disabled. . Note: experimental API that can change or be removed without any prior notice. Returns new instance of with Flags set to the value provided. Values of all other fields are preserved. The call flags. Options for . The context propagation options that will be used by default. Creates new context propagation options. If set to true parent call's deadline will be propagated to the child call. If set to true parent call's cancellation token will be propagated to the child call. true if parent call's deadline should be propagated to the child call. true if parent call's cancellation token should be propagated to the child call. Token for propagating context of server side handlers to child calls. In situations when a backend is making calls to another backend, it makes sense to propagate properties like deadline and cancellation token of the server call to the child call. Underlying gRPC implementation may provide other "opaque" contexts (like tracing context) that are not explicitly accesible via the public C# API, but this token still allows propagating them. Provides access to the payload being deserialized when deserializing messages. Get the total length of the payload in bytes. Gets the entire payload as a newly allocated byte array. Once the byte array is returned, the byte array becomes owned by the caller and won't be ever accessed or reused by gRPC again. NOTE: Obtaining the buffer as a newly allocated byte array is the simplest way of accessing the payload, but it can have important consequences in high-performance scenarios. In particular, using this method usually requires copying of the entire buffer one extra time. Also, allocating a new buffer each time can put excessive pressure on GC, especially if the payload is more than 86700 bytes large (which means the newly allocated buffer will be placed in LOH, and LOH object can only be garbage collected via a full ("stop the world") GC run). NOTE: Deserializers are expected not to call this method (or other payload accessor methods) more than once per received message (as there is no practical reason for doing so) and DeserializationContext implementations are free to assume so. byte array containing the entire payload. A stream of messages to be read. Messages can be awaited await reader.MoveNext(), that returns true if there is a message available and false if there are no more messages (i.e. the stream has been closed). On the client side, the last invocation of MoveNext() either returns false if the call has finished successfully or throws RpcException if call finished with an error. Once the call finishes, subsequent invocations of MoveNext() will continue yielding the same result (returning false or throwing an exception). On the server side, MoveNext() does not throw exceptions. In case of a failure, the request stream will appear to be finished (MoveNext will return false) and the CancellationToken associated with the call will be cancelled to signal the failure. MoveNext() operations can be cancelled via a cancellation token. Cancelling an individual read operation has the same effect as cancelling the entire call (which will also result in the read operation returning prematurely), but the per-read cancellation tokens passed to MoveNext() only result in cancelling the call if the read operation haven't finished yet. The message type. A writable stream of messages. The message type. Writes a single asynchronously. Only one write can be pending at a time. the message to be written. Cannot be null. Write options that will be used for the next write. If null, default options will be used. Once set, this property maintains its value across subsequent writes.

OK indicates success, all other values indicate an error. Gets the detail. Returns a that represents the current . Result of a remote procedure call. Based on grpc_status_code from grpc/status.h Not an error; returned on success. The operation was cancelled (typically by the caller). Unknown error. An example of where this error may be returned is if a Status value received from another address space belongs to an error-space that is not known in this address space. Also errors raised by APIs that do not return enough error information may be converted to this error. Client specified an invalid argument. Note that this differs from FAILED_PRECONDITION. INVALID_ARGUMENT indicates arguments that are problematic regardless of the state of the system (e.g., a malformed file name). Deadline expired before operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully. For example, a successful response from a server could have been delayed long enough for the deadline to expire. Some requested entity (e.g., file or directory) was not found. Some entity that we attempted to create (e.g., file or directory) already exists. The caller does not have permission to execute the specified operation. PERMISSION_DENIED must not be used for rejections caused by exhausting some resource (use RESOURCE_EXHAUSTED instead for those errors). PERMISSION_DENIED must not be used if the caller can not be identified (use UNAUTHENTICATED instead for those errors). The request does not have valid authentication credentials for the operation. Some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space. Operation was rejected because the system is not in a state required for the operation's execution. For example, directory to be deleted may be non-empty, an rmdir operation is applied to a non-directory, etc. The operation was aborted, typically due to a concurrency issue like sequencer check failures, transaction aborts, etc. Operation was attempted past the valid range. E.g., seeking or reading past end of file. Operation is not implemented or not supported/enabled in this service. Internal errors. Means some invariants expected by underlying system has been broken. If you see one of these errors, something is very broken. The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff. Note that it is not always safe to retry non-idempotent operations. Unrecoverable data loss or corruption. Utility methods to simplify checking preconditions in the code.
