Module tonic::client

Expand description

Generic client implementation.

This module contains the low level components to build a gRPC client. It provides a codec agnostic gRPC client dispatcher and a decorated tower service trait.

This client is generally used by some code generation tool to provide stubs for the gRPC service. Thusly, they are a bit cumbersome to use by hand.

§Concurrent usage

Upon using the your generated client, you will discover all the functions corresponding to your rpc methods take &mut self, making concurrent usage of the client difficult. The answer is simply to clone the client, which is cheap as all client instances will share the same channel for communication. For more details, see transport::Channel.
