Crate grpcio

grpcio is a Rust implementation of gRPC, which is a high performance, open source universal RPC framework that puts mobile and HTTP/2 first. grpcio is built on gRPC Core and futures-rs.

Optional features

• secure (enabled by default) - Enables support for TLS encryption and some authentication mechanisms.

Structs

AuthContext	To perform server-side authentication, gRPC exposes the authentication context for each call. The context exposes important authentication-related information about the RPC such as the type of security/authentication type being used and the peer identity.
AuthProperty	Auth properties are elements of the AuthContext. They have a name (a key of type string) and a value which can be a string or binary data.
AuthPropertyIter
CallOption	Options for calls made by client.
Channel	A gRPC channel.
ChannelBuilder	Channel factory in order to configure the properties.
ChannelCredentials	Client-side SSL credentials.
ChannelCredentialsBuilder	ChannelCredentials factory in order to configure the properties.
Client	A generic client for making RPC calls.
ClientCStreamReceiver	A receiver for client streaming call.
ClientDuplexReceiver	A response receiver for duplex call.
ClientSStreamReceiver	A receiver for server streaming call.
ClientStreamingSink	A sink for client streaming call.
ClientStreamingSinkResult
ClientUnaryReceiver	A receiver for unary request.
Deadline	A time point that an rpc or operation should finished before it.
DuplexSink	A sink for duplex streaming call.
DuplexSinkFailure
EnvBuilder	Environment factory in order to configure the properties.
Environment	An object that used to control concurrency and start gRPC event loop.
GrpcSlice	A convenient rust wrapper for the type grpc_slice.
Marshaller	Defines how to serialize and deserialize between the specialized type and byte slice.
Metadata	A collection of metadata entries that can be exchanged during a call.
MetadataBuilder	Builder for immutable Metadata.
MetadataIter	Immutable metadata iterator
Method	A description of a remote method.
RequestStream	A stream for client a streaming call and a duplex streaming call.
ResourceQuota	ResourceQuota represents a bound on memory and thread usage by the gRPC. NOTE: The management of threads created in grpc-core don’t use ResourceQuota. TODO: Manage the poller threads created in grpc-rs with this ResourceQuota later.
RpcContext	A context for rpc handling.
RpcStatus	RPC result returned from the server.
RpcStatusCode	An gRPC status code structure. This type contains constants for all gRPC status codes.
Server	A gRPC server.
ServerBuilder	Server factory in order to configure the properties.
ServerCredentials	Server-side SSL credentials.
ServerCredentialsBuilder	ServerCredentials factory in order to configure the properties.
ServerStreamingSink	A sink for server streaming call.
ServerStreamingSinkFailure
Service	A gRPC service.
ServiceBuilder	Service factory in order to configure the properties.
ShutdownFuture	A Future that will resolve when shutdown completes.
StreamingCallSink	A sink for client streaming call and duplex streaming call. To close the sink properly, you should call close before dropping.
UnarySink	A sink for unary call.
UnarySinkResult
WriteFlags	Flags for write operations.

Enums

CertificateRequestType
CheckResult	Used to indicate the result of the check. If it returns Abort, skip the subsequent checkers and abort the grpc call.
CompressionAlgorithms	The various compression algorithms supported by gRPC (not sorted by compression level)
CompressionLevel	Compression levels allow a party with knowledge of its peer’s accepted encodings to request compression in an abstract way. The level-algorithm mapping is performed internally and depends on the peer’s supported compression algorithms.
ConnectivityState	Connectivity state of a channel.
Error	Errors generated from this library.
LbPolicy
MethodType	Method types supported by gRPC.
OptTarget	The optimization target for a Channel.

Traits

ServerChecker
ServerCredentialsFetcher	Traits to retrieve updated SSL server certificates, private keys, and trusted CAs (for client authentication).

Functions

pb_de
pb_ser
redirect_log	Redirect grpc log to rust’s log implementation.

Type Definitions

ClientCStreamSender	A sink for client streaming call.
ClientDuplexSender	A sink for duplex streaming call.
MessageReader
Result	Type alias to use this library’s Error type in a Result.
