Declare functions in Rust and expose them to C#.

#[cs_bindgen]
pub fn greet(name: String) -> String {
    format!("Hello, {}!", name)
}

Call into Rust code from C# as if it were idiomatic C#!

var greeting = Example.Greet("Ferris");

// Prints "Hello, Ferris!"
Console.WriteLine(greeting);

Highly experimental! Do not use, even as a joke!

• Make sure you have the latest version of Rust installed:

  rustup update
  

• Install the wasm32-unknown-unknown toolchain:

  rustup target add wasm32-unknown-unknown
  

• Make sure you have the .NET Core CLI installed if you're going to run the integration test suite.

In addition to the usual Rust testing setup that can be run via cargo run, there's a more complete integration test setup that builds C# bindings into a .NET Core project and uses xUnit to test that the Rust binary can be embedded correctly. To setup the bindings for the tests, first run:

cargo run -p builder

Then, to run the tests, navigate to the integration-tests/TestRunner directory and run:

dotnet test
