Duchess is a Rust crate that makes it easy, ergonomic, and efficient to interoperate with Java code.

Duchess permits you to reflect Java classes into Rust and easily invoke methods on Java objects. For example the following Java code...

Logger logger = new log.Logger();
logger.addEvent(
    Event.builder()
        .withTime(new Date())
        .withName("foo")
        .build()
);

...could be executed in Rust as follows:

let logger = log::Logger::new().execute()?;
logger
    .add_event(
        log::Event::builder()
            .with_time(java::util::Date::new())
            .with_name("foo")
            .build(),
    )
    .execute()?;
