Enum rsonpath::query::automaton::TransitionLabel

pub enum TransitionLabel<'q> {
    ObjectMember(&'q JsonString),
    ArrayIndex(NonNegativeArrayIndex),
}

Represent the distinct methods of moving on a match between states.

Variants

ObjectMember(&'q JsonString)

Transition when a JSON member name matches a JsonStringi.

ArrayIndex(NonNegativeArrayIndex)

Transition on the n-th element of an array, with n specified by a NonNegativeArrayIndex.

Implementations

impl<'q> TransitionLabel<'q>

pub fn get_member_name(&self) -> Option<&'q JsonString>

Return the textual JsonString being wrapped if so. Returns None otherwise.

pub fn get_array_index(&'q self) -> Option<&'q NonNegativeArrayIndex>

Return the NonNegativeArrayIndex being wrapped if so. Returns None otherwise.

pub fn new_object_member(member_name: &'q JsonString) -> Self

Wraps a JsonString in a TransitionLabel.

pub fn new_array_index(index: NonNegativeArrayIndex) -> Self

Wraps a NonNegativeArrayIndex in a TransitionLabel.

Trait Implementations

impl<'q> Clone for TransitionLabel<'q>

fn clone(&self) -> TransitionLabel<'q>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'q> Debug for TransitionLabel<'q>

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

Formats the value using the given formatter.

impl Display for TransitionLabel<'_>

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

Formats the value using the given formatter.

impl<'q> From<&'q JsonString> for TransitionLabel<'q>

fn from(member_name: &'q JsonString) -> Self

Converts to this type from the input type.

impl<T: Borrow<NonNegativeArrayIndex>> From<T> for TransitionLabel<'_>

fn from(index: T) -> Self

Converts to this type from the input type.

impl<'q> PartialEq<TransitionLabel<'q>> for TransitionLabel<'q>

fn eq(&self, other: &TransitionLabel<'q>) -> 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.
