Examples

Set of examples that show off the features provided by tonic.

In order to build these examples, you must have the protoc Protocol Buffers compiler installed, along with the Protocol Buffers resource files.

Ubuntu:

sudo apt update && sudo apt upgrade -y
sudo apt install -y protobuf-compiler libprotobuf-dev

Alpine Linux:

sudo apk add protoc protobuf-dev

macOS:

Assuming Homebrew is already installed. (If not, see instructions for installing Homebrew on the Homebrew website.)

brew install protobuf

Helloworld

Client

$ cargo run --bin helloworld-client

Server

Autoreloading Server

Server

systemfd --no-pid -s http::[::1]:50051 -- cargo watch -x 'run --bin autoreload-server'

Notes:

If you are using the codegen feature, then the following dependencies are required:

• bytes
• prost
• prost-derive

The autoload example requires the following crates installed globally:

• systemfd
• cargo-watch

Richer Error

Both clients and both servers do the same thing, but using the two different approaches. Run one of the servers in one terminal, and then run the clients in another.

Client using the ErrorDetails struct

$ cargo run --bin richer-error-client

Client using a vector of error message types

$ cargo run --bin richer-error-client-vec

Server using the ErrorDetails struct

$ cargo run --bin richer-error-server

Server using a vector of error message types

$ cargo run --bin richer-error-server-vec
