Enum Segment

pub enum Segment {
    Child(Selectors),
    Descendant(Selectors),
}

JSONPath query segment.

Every query is a sequence of zero or more of segments, each applying one or more selectors to a node and passing it along to the subsequent segments.

Variants

Child(Selectors)

A child segment contains a sequence of selectors, each of which selects zero or more children of a node.

Descendant(Selectors)

A child segment contains a sequence of selectors, each of which selects zero or more descendants of a node.

Implementations

impl Segment

pub fn selectors(&self) -> &Selectors

Returns all Selector instances of the segment.

pub fn is_child(&self) -> bool

Check if this is a child segment.

Examples

let segment = Segment::Child(Selectors::one(Selector::Wildcard));
assert!(segment.is_child());

pub fn is_descendant(&self) -> bool

Check if this is a descendant segment.

Examples

let segment = Segment::Descendant(Selectors::one(Selector::Wildcard));
assert!(segment.is_descendant());

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for Segment

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for Segment

fn clone(&self) -> Segment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Segment

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Segment

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Segment

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

Formats the value using the given formatter.

impl From<SingularSegment> for Segment

fn from(value: SingularSegment) -> Self

Converts to this type from the input type.

impl FromIterator<Segment> for JsonPathQuery

fn from_iter<T: IntoIterator<Item = Segment>>(iter: T) -> Self

Creates a value from an iterator.

impl Hash for Segment

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 Segment

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

impl Serialize for Segment

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Segment
