[−][src]Struct jni_glue::Ref

pub struct Ref<'env, Class: AsValidJObjectAndEnv> { /* fields omitted */ }

A non-null, reference to a Java object (+ &Env). This may refer to a Local, Global, local Argument, etc.

Not FFI Safe: #[repr(rust)], and exact layout is likely to change - depending on exact features used - in the future. Specifically, on Android, since we're guaranteed to only have a single ambient VM, we can likely store the *const JNIEnv in thread local storage instead of lugging it around in every Local. Of course, there's no guarantee that's actually an optimization...
