NativeHandleGuard 0.86.4 API

All Implemented Interfaces:

java.lang.AutoCloseable
```
public class NativeHandleGuard
 implements AutoCloseable
                    
```
Provides access to a Rust object handle while keeping the Java wrapper alive.
Intended for use with try-with-resources syntax. NativeHandleGuard prevents the Java wrapper from being finalized, which would destroy the Rust object, while the handle is in use. To use it, the Java wrapper type should conform to the NativeHandleGuard.Owner interface.
Note that it is not necessary to use NativeHandleGuard in the implementation of finalize itself. The point of NativeHandleGuard is to delay finalization while the Rust object is being used; once finalization has begun, there can be no other uses of the Rust object from Java.
