Struct rsonpath_lib::query::automaton::StateAttributes

pub struct StateAttributes(_);

A set of attributes that can be associated with a State.

Implementations

impl StateAttributes

pub const ACCEPTING: Self = _

Marks that the State is accepting.

pub const EMPTY: Self = _

Set with no attributes.

pub const REJECTING: Self = _

Marks that the State is rejecting, i.e. there is no possible path to any accepting state from it.

pub const TRANSITIONS_TO_ACCEPTING: Self = _

Marks that the State contains some transition (labelled or fallback) to an Accepting state.

pub const UNITARY: Self = _

Marks that the State is unitary. A state is unitary if it contains exactly one labelled transition and its fallback transition is Rejecting.

pub fn is_accepting(&self) -> bool

Check if the the state is accepting.

pub fn is_rejecting(&self) -> bool

Check if the state is rejecting, i.e. there is no possible path to any accepting state from it.

pub fn has_transition_to_accepting(&self) -> bool

Marks that the State contains some transition (labelled or fallback) to an Accepting state.

pub fn is_unitary(&self) -> bool

Marks that the State is unitary. A state is unitary if it contains exactly one labelled transition and its fallback transition is Rejecting.

Trait Implementations

impl BitOr<StateAttributes> for StateAttributes

type Output = StateAttributes

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl Clone for StateAttributes

fn clone(&self) -> StateAttributes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StateAttributes

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

Formats the value using the given formatter.

impl Default for StateAttributes

fn default() -> StateAttributes

Returns the “default value” for a type.

impl Hash for StateAttributes

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<StateAttributes> for StateAttributes

fn eq(&self, other: &StateAttributes) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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