Struct Cap 

pub struct Cap<'a> {
    pub component: &'a str,
    pub action: &'a str,
    pub scope: Option<&'a str>,
}

A parsed capability string.

Fields

component: &'a str

The component, e.g. camera.

action: &'a str

The action, e.g. snapshot.

scope: Option<&'a str>

Optional scope, e.g. front-door.
