Enum TransitionOutcome 

pub enum TransitionOutcome<T> {
    None,
    Pushed,
    Revealed(Vec<T>),
    SwappedIn(Vec<T>, usize),
}

What happened to the state stack after applying a transition.

Variants

None

Nothing happened!

Pushed

A state was newly pushed to the stack.

Revealed(Vec<T>)

The top state on the stack was revealed after things were removed from on top of it. The Vec has all the states that used to be on top, with the last element being the previous top of the stack.

SwappedIn(Vec<T>, usize)

Things were removed from the stack, and then the new state got pushed on top along with N things below it.

Trait Implementations

impl<T: Clone> Clone for TransitionOutcome<T>

fn clone(&self) -> TransitionOutcome<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for TransitionOutcome<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for TransitionOutcome<T>

fn eq(&self, other: &TransitionOutcome<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
