Struct StateTransitionSet 

pub struct StateTransitionSet<S>
where
    S: Copy + Eq + Hash,
{ /* private fields */ }

Reusable collection that matches state pairs to transition timelines.

Implementations

impl<S> StateTransitionSet<S>

where S: Copy + Eq + Hash,

pub fn new() -> Self

Creates an empty transition set.

pub fn from_transitions( transitions: impl IntoIterator<Item = StateTransition<S>>, ) -> Self

Creates a transition set from an iterator of transitions.

pub fn with_fallback(self, fallback: Timeline) -> Self

Sets the fallback timeline used when no state-pair transition matches.

pub fn push(&mut self, transition: StateTransition<S>)

Adds a transition to the set.

pub fn transitions(&self) -> &[StateTransition<S>]

Returns all transitions in insertion order.

pub fn fallback(&self) -> Option<&Timeline>

Returns the fallback timeline, if one is configured.

pub fn find(&self, from: S, to: S) -> Option<&StateTransition<S>>

Returns the first transition matching from and to.

Trait Implementations

impl<S> Clone for StateTransitionSet<S>

where S: Copy + Eq + Hash + Clone,

fn clone(&self) -> StateTransitionSet<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S> Debug for StateTransitionSet<S>

where S: Copy + Eq + Hash + Debug,

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

Formats the value using the given formatter.

impl<S> Default for StateTransitionSet<S>

where S: Copy + Eq + Hash,

fn default() -> Self

Returns the “default value” for a type.

impl<S> From<Vec<StateTransition<S>>> for StateTransitionSet<S>

where S: Copy + Eq + Hash,

fn from(value: Vec<StateTransition<S>>) -> Self

Converts to this type from the input type.

impl<S> PartialEq for StateTransitionSet<S>

where S: Copy + Eq + Hash + PartialEq,

fn eq(&self, other: &StateTransitionSet<S>) -> 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.
