jni 0.20.0

Rust JNI 0.20.0

on Rust Cargo

Added

• Default trait implemented for JObject, JString, JClass, and JByteBuffer (#199)
• Debug trait implemented for JavaVM, GlobalRef, GlobalRefGuard, JStaticMethodID and ReleaseMode (#345)
• ReturnType for specifying object return types without a String allocation. (#329)

Changed

• The release_string_utf_chars function has been marked as unsafe. (#334)
• Mark JNIEnv::new_direct_byte_buffer as unsafe (#320)
• JNIEnv::new_direct_byte_buffer now takes a raw pointer and size instead of a slice (#351 and #364)
• JNIEnv::direct_buffer_address returns a raw pointer instead of a slice (#364)
• The lifetime of AutoArray is no longer tied to the lifetime of a particular JNIEnv reference. (#302)
• Relaxed lifetime restrictions on JNIEnv::new_local_ref. Now it can be used to create a local
  reference from a global reference. (#301 / #319)
• JMethodID and JStaticMethodID implement Send + Sync and no longer has a lifetime parameter, making method
  IDs cacheable (with a documented 'Safety' note about ensuring they remain valid). (#346)
• JFieldID and JStaticFieldID implement Send + Sync and no longer has a lifetime parameter, making field
  IDs cacheable (with a documented 'Safety' note about ensuring they remain valid). (#346)
• The call_*_method_unchecked functions now take jni:sys::jvalue arguments to avoid allocating
  a Vec on each call to map + collect JValues as sys:jvalues (#329)
• The From trait implementations converting jni_sys types like jobject to JObject have been replaced
  with unsafe ::from_raw functions and corresponding ::into_raw methods. Existing ::into_inner APIs were
  renamed ::into_raw for symmetry. (#197)
• The APIs JNIEnv::set_rust_field, JNIEnv::get_rust_field and JNIEnv::take_rust_field have been marked as unsafe (#219)
