Crate java_spaghetti

Common glue code between Rust and JNI, used in autogenerated java-spaghetti glue code.

See also the Android JNI tips documentation as well as the Java Native Interface Specification.

Re-exports

• pub use ::jni_sys as sys;

Structs

• Arg
  FFI: Use Arg<java::lang::Object> instead of jobject. This represents a (null?) function argument.
• BooleanArray
  A PrimitiveArray implementation.
• ByteArray
  A PrimitiveArray implementation.
• CastError
  Error returned on failed .cast().`
• CharArray
  A PrimitiveArray implementation.
• DoubleArray
  A PrimitiveArray implementation.
• Env
  FFI: Use Env instead of *const JNIEnv. This represents a per-thread Java exection environment.
• FloatArray
  A PrimitiveArray implementation.
• Global
  A Global, non-null, reference to a Java object (+ VM).
• IntArray
  A PrimitiveArray implementation.
• Local
  A Local, non-null, reference to a Java object (+ Env) limited to the current thread/stack.
• LongArray
  A PrimitiveArray implementation.
• Null
• ObjectArray
  A Java Array of reference types (classes, interfaces, other arrays, etc.)
• ObjectArrayIter
• Ref
  A non-null, reference to a Java object (+ Env). This may refer to a Local, Global, local Arg, etc.
• Return
  FFI: Use Return<java::lang::Object> instead of jobject. This represents a (null?) JNI function call return value.
• ShortArray
  A PrimitiveArray implementation.
• StringChars
  Represents an env.GetStringChars + env.GetStringLength query. Will automatically env.ReleaseStringChars when dropped.
• VM
  FFI: Use &VM instead of *const JavaVM. This represents a global, process-wide Java exection environment.

Traits

• AsArg
• AssignableTo
  Marker trait indicating Self can be assigned to T.
• JniType
  JNI bindings rely on this type being accurate.
• PrimitiveArray
  A Java Array of some POD-like type such as bool, jbyte, jchar, jshort, jint, jlong, jfloat, or jdouble.
• ThrowableType
  A marker type indicating this is a valid exception type that all exceptions thrown by java should be compatible with
