Trait Desc

pub trait Desc<'a, T> {
    // Required method
    fn lookup(self, _: &JNIEnv<'a>) -> Result<T>;
}

see https://github.com/jni-rs/jni-rs/blob/master/src/wrapper/descriptors/desc.rs

Trait for things that can be looked up through the JNI via a descriptor. This will be something like the fully-qualified class name java/lang/String or a tuple containing a class descriptor, method name, and method signature. For convenience, this is also implemented for the concrete types themselves in addition to their descriptors.

Required Methods

fn lookup(self, _: &JNIEnv<'a>) -> Result<T>

Different Look up the concrete type from the JVM.
