}Expand description
Query parameters should be hashable and clonable.
The hash infrastructure is part of this trait itself, because it’s not unlikely you want to hash the elements you pass into queries in a different way than they are hashed by default.
Required Methods§
fn hash_stable(&self, hasher: &mut QueryHasher)
Provided Methods§
fn get_clone<'cx>() -> for<'a> fn(this: TypeErasedQueryParam<'cx>, _: &'a Storage) -> TypeErasedQueryParam<'a>where
Self: 'cx,
Object Safety§
This trait is not object safe.
