Trait Policy 

pub trait Policy<M>:
    Send
    + Sync
    + 'static {
    // Required method
    fn allows(&self, cx: &Cx, ability: Ability<'_, M>) -> bool;
}

Decides which Abilitys the current user has over a resource’s records.

A closure |cx: &Cx, ability: Ability<'_, M>| -> bool is a policy, and the building blocks combine with and and or.

Required Methods

fn allows(&self, cx: &Cx, ability: Ability<'_, M>) -> bool

Whether the current user may do ability.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
