Trait FromJavaValue 

pub trait FromJavaValue<'j, J>: Sized {
    // Required method
    fn from_jvalue(env: JNIEnv<'j>, jvalue: JValue<'j>) -> Self;
}

Convert from a JValue (return type in Java) into the Rust type

This is infallible because the generated code using it should “know” that the type is already correct

Required Methods

fn from_jvalue(env: JNIEnv<'j>, jvalue: JValue<'j>) -> Self

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.
