PolicyHandler

Struct PolicyHandler 

Source
pub struct PolicyHandler<T: Send + Sync + 'static> { /* private fields */ }
Expand description

A registered power-policy handler bound to a static state cell.

Construct with PolicyHandler::new and register with set_policy. The handler must be 'static (typically declared at module scope with crate::shared! + this type).
