jni-bindgen

Work in progress, only barely kinda partially usable

Vaguely inspired by, but otherwise unrelated to, bindgen and wasm-bindgen's WebIDL stuff.

Generate Rust JVM FFI wrappers around APIs defined by .jar or .class files, because maintaining your own hand-written bindings is an exercise in boredom, soundness bugs, and pain.

Goals

• Provide a means of using Android system APIs specifically.
• Provide a means of using Java, Kotlin, Scala, or other JVM based APIs.
• Automatically link API documentation, so people might actually read it.
• Eliminate the need to manually write unsound, unreviewed, and unaudited unsafe { ... } APIs
