Trait Cast 

pub trait Cast<'env, As: Cast<'env, Object<'env>>>:
    JavaType<__JniType = jobject>
    + ToJni
    + FromJni<'env> {
    // Required method
    fn cast<'a>(&'a self) -> &'a As;
}

A trait for casting Java object types to their superclasses.

Required Methods

fn cast<'a>(&'a self) -> &'a As

Cast the object to itself or one of it’s superclasses.

Doesn’t actually convert anything, the result is just the same object interpreted as one of it’s superclasses.

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.
