Enum Seg 

pub enum Seg {
    Key(String),
    Index(usize),
}

A single segment in a JSON path.

Variants

Key(String)

Object key access: {"key": value}

Index(usize)

Array index access: [index]

Implementations

impl Seg

pub fn key(k: impl Into<String>) -> Self

Create a key segment.

pub fn index(i: usize) -> Self

Create an index segment.

pub fn is_key(&self) -> bool

Returns true if this is a key segment.

pub fn is_index(&self) -> bool

Returns true if this is an index segment.

pub fn as_key(&self) -> Option<&str>

Get the key if this is a key segment.

pub fn as_index(&self) -> Option<usize>

Get the index if this is an index segment.

Trait Implementations

impl Clone for Seg

fn clone(&self) -> Seg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Seg

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Seg

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Seg

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

Formats the value using the given formatter.

impl From<&str> for Seg

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for Seg

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<usize> for Seg

fn from(i: usize) -> Self

Converts to this type from the input type.

impl FromIterator<Seg> for Path

fn from_iter<I: IntoIterator<Item = Seg>>(iter: I) -> Self

Creates a value from an iterator.

impl Hash for Seg

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 Ord for Seg

fn cmp(&self, other: &Seg) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Seg

fn eq(&self, other: &Seg) -> 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 PartialOrd for Seg

fn partial_cmp(&self, other: &Seg) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Seg

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 Seg

impl StructuralPartialEq for Seg
