Trait ObjectExt 

pub trait ObjectExt<'js> {
    // Required method
    fn get_optional<K: IntoAtom<'js> + Clone, V: FromJs<'js>>(
        &self,
        k: K,
    ) -> Result<Option<V>>;
}

Required Methods

fn get_optional<K: IntoAtom<'js> + Clone, V: FromJs<'js>>( &self, k: K, ) -> Result<Option<V>>

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.
