Enum TransitionType 

pub enum TransitionType {
    Range(CharRange),
    NotRange(CharRange),
    Epsilon,
}

The type of a transition in a nondeterministic finite automaton. Every transition in an automaton is labeled with a type that determines the behavior of the transition. The type can be a character range, a negated character range, or an epsilon transition. For a character range transition, the transition is taken if the input character is in the range. For a negated character range transition, the transition is taken if the input character is not in the range. An epsilon transition is taken without consuming any input.

Variants

Range(CharRange)

A transition that is taken if the input character is in the given range.

NotRange(CharRange)

A transition that is taken if the input character is not in the given range.

Epsilon

An epsilon transition that is taken without consuming any input.

Implementations

impl TransitionType

pub fn is_epsilon(&self) -> bool

Returns true if the transition is an epsilon transition.

pub fn is_empty(&self) -> bool

Returns true if the transition is an empty transition, i.e. a transition that can never be taken.

Trait Implementations

impl Clone for TransitionType

fn clone(&self) -> TransitionType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransitionType

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

Formats the value using the given formatter.

impl Display for TransitionType

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

Formats the value using the given formatter.

impl Hash for TransitionType

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 TransitionType

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