Trait SMut 

pub trait SMut: SRef + MayTransition {
    // Required method
    fn s_mut<T, State>(inner: &mut Self::Inner<T, State>) -> &mut T
       where T: StateMachineImpl;
}

Storage backend that can expose a mutable runtime reference.

Use S: SMut for methods that mutate runtime data or call transition!. Transition effect bodies always receive &mut T, so a transition method normally needs this bound even if the body is empty.

Required Methods

fn s_mut<T, State>(inner: &mut Self::Inner<T, State>) -> &mut T

where T: StateMachineImpl,

Mutably borrows the runtime implementation from this storage backend.

Dyn Compatibility

This trait is not dyn compatible.

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