Struct jni::objects::JMethodID

#[repr(transparent)]
pub struct JMethodID<'a> { /* private fields */ }

Wrapper around sys::jmethodid that adds a lifetime. This prevents it from outliving the context in which it was acquired and getting GC’d out from under us. It matches C’s representation of the raw pointer, so it can be used in any of the extern function argument positions that would take a jmethodid.
