# Rust
|
|
|
|
The Rust project is built using Cargo which manages dependencies between the
|
|
projects as well as external dependencies and allows for incremental
|
|
compilation. The build configuration is defined in
|
|
[`Cargo.toml`](../../Cargo.toml).

# Java Native Interface
|
|
|
|
Although the entry point of the Enso project is a Java archive, it can still
|
|
make use of native libraries built in Rust trough the JVM foreign function
|
|
interface (FFI) named
|
|
[Java Native Interface](https://en.wikipedia.org/wiki/Java_Native_Interface)
|
|
(JNI).
|
|
|
|
In order to generate a shared library, the `Cargo.toml` needs to enable
|
|
compilation into a dynamic system library:
|
|
|
|
```
|
|
crate-type = ["cdylib"]
|
|
```
|
|
|
|
Invoking `cargo build` will then output the library into `target/rust/debug`
|
|
with the extension `.so` on Linux, `.dll` on Windows and `.dylib` on macOS.
|
|
|
|
Then, to be able to load the library by `System.loadLibrary("lib_name")`, the
|
|
Java application should be started with the option
|
|
`-Djava.library.path=path/to/lib_folder`.
