A RAII implementation of scoped guard which detaches the current thread
when dropped. The attached JNIEnv can be accessed through this guard
via its Deref implementation.
A global JVM reference. These are “pinned” by the garbage collector and are
guaranteed to not get collected until released. Thus, this is allowed to
outlive the JNIEnv that it came from and can be used in other threads.
Lifetime’d representation of a jclass. Just a JObject wrapped in a new
class.
FFI-compatible JNIEnv struct. You can safely use this as the JNIEnv argument
to exported methods that will be called by java. This is where most of the
magic happens. All methods on this object are wrappers around JNI functions,
so the documentation on their behavior is still pretty applicable.
Wrapper around [sys::jobject] that adds a lifetime to ensure that
the underlying JNI pointer won’t be accessible to safe Rust code if the
object reference is released.
Lifetime’d representation of a jstring. Just a JObject wrapped in a new
class.
Native method descriptor.
