There are several reasons why integrating Rust into other languages might be interesting. Rust is often used for computationally intensive applications, better control over memory management, or for accessing low-level hardware.

Integrating Rust with other languages allows to get the best of both worlds, the power and safety of Rust as well as - for example - the advantages of a managed language like Java.

Another good reason is extending or migrating existing applications with/to Rust.

This talk provides a tour of some of what is out there in the Rust ecosystem to bridge the worlds between Rust, Java, C, and C++.
