Struct serde_pointer::Pointer

pub struct Pointer { /* fields omitted */ }

Represents a pointer to the data as defined in the RFC6901 - the JSON Pointer specification.

Methods

impl Pointer

pub fn push(&mut self, step: Step) -> &mut Self

pub fn pop(&mut self) -> Option<Step>

pub fn insert(&mut self, index: usize, step: Step)

pub fn remove(&mut self, index: usize) -> Step

pub fn traverse<'a>(&self, val: &'a Value) -> Option<ValuePointer<'a>>

Traverses the provided value and finds the data this pointer points to in it, if any.

pub fn traverse_mut<'a>(
    &self,
    val: &'a mut Value
) -> Option<ValuePointerMut<'a>>

pub fn find<'a>(&self, val: &'a Value) -> Option<&'a Value>

A simple override of traverse() that directly exposes the found value, if any.

pub fn find_mut<'a>(&self, val: &'a mut Value) -> Option<&'a mut Value>

Trait Implementations

impl From<Vec<Step>> for Pointer

fn from(ps: Vec<Step>) -> Self

Performs the conversion.

impl Into<Vec<Step>> for Pointer

fn into(self) -> Vec<Step>

Performs the conversion.

impl IntoIterator for Pointer

type Item = Step

The type of the elements being iterated over.

type IntoIter = IntoIter<Step>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Clone for Pointer

fn clone(&self) -> Pointer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Pointer

fn default() -> Self

Returns the "default value" for a type.

impl Eq for Pointer

impl PartialEq<Pointer> for Pointer

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

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

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

This method tests for !=.

impl PartialOrd<Pointer> for Pointer

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Debug for Pointer

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

Formats the value using the given formatter.

impl FromStr for Pointer

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.
