Trait IntoJava 

pub trait IntoJava<'j> {
    type Ret;

    // Required method
    fn into_java(self, _: &mut JNIEnv<'j>) -> Result<Self::Ret, Error>;
}

Specifies how a Rust type should be converted into a Java primitive.

Required Associated Types

type Ret

The JNI type representing the output.

Required Methods

fn into_java(self, _: &mut JNIEnv<'j>) -> Result<Self::Ret, Error>

Attempts to convert this Rust object into a Java primitive.

Dyn Compatibility

This trait is dyn compatible.

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