Enum TransitionKind 

pub enum TransitionKind {
    Epsilon,
    Consume,
    CounterReset(CounterId),
    CounterIncrement(CounterId),
    CounterMaxGuard(CounterId),
    CounterMinGuard(CounterId),
}

Type of transition between NFA states

Variants

Epsilon

Epsilon transition (no input consumed, always available)

Consume

Consuming transition (requires matching the target state’s term)

CounterReset(CounterId)

Reset a counter to 0 (entering a counted region)

CounterIncrement(CounterId)

Increment a counter by 1 (completed one loop iteration)

CounterMaxGuard(CounterId)

Guard: pass only if counter < def.max (loop back)

CounterMinGuard(CounterId)

Guard: pass only if counter >= def.min (exit loop)

Implementations

impl TransitionKind

pub fn is_epsilon_like(&self) -> bool

Check if this transition is epsilon-like (does not consume input). All counter transitions are epsilon-like; only Consume is not.

pub fn offset_counter(self, offset: CounterId) -> Self

Offset counter IDs by the given amount (for fragment/table composition). Returns self unchanged for non-counter transitions.

Trait Implementations

impl Clone for TransitionKind

fn clone(&self) -> TransitionKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TransitionKind

impl Debug for TransitionKind

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

Formats the value using the given formatter.

impl Eq for TransitionKind

impl Hash for TransitionKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TransitionKind

fn eq(&self, other: &TransitionKind) -> 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.
