Trait IntoJavaObject

pub trait IntoJavaObject<'j> {
    const CLASS: &'static str;

    // Required method
    fn into_java_object(
        self,
        env: &mut JNIEnv<'j>,
    ) -> Result<JObject<'j>, Error>;
}

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

Required Associated Constants

const CLASS: &'static str

The Java class associated with this type.

Required Methods

fn into_java_object(self, env: &mut JNIEnv<'j>) -> Result<JObject<'j>, Error>

Attempts to convert this Rust object into a Java object.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
