Primitive java values that can be cheaply converted to / from JValue and can be wrapped by an Object class.

Required Associated Types

type PrimitiveWrapper: Class

The Object type that this type may be wrapped with

Required Methods

fn to_primitive_wrapper(&self, e: &mut Env<'_>) -> Self::PrimitiveWrapper

Create a new instance of Self::PrimitiveWrapper from a copy of self

fn from_primitive_wrapper(e: &mut Env<'_>, w: Self::PrimitiveWrapper) -> Self

Perform the inverse conversion, yielding Self from Self::PrimitiveWrapper

fn from_jvalue_ref(jv: JValue<'_, '_>) -> Self

Convert a local JValue reference to Self

fn from_jvalue(jv: JValueOwned<'_>) -> Self

Convert an owned local JValue to Self

fn into_jvalue<'local>(self) -> JValueOwned<'local>

Convert self to a JValue

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
