Struct json_pointer::JsonPointer

pub struct JsonPointer<S: AsRef<str>, C: AsRef<[S]>> { /* fields omitted */ }

A JSON Pointer.

Create a new JSON pointer with JsonPointer::new, or parse one from a string with str::parse().

Methods

impl<S: AsRef<str>, C: AsRef<[S]>> JsonPointer<S, C>

fn new(ref_toks: C) -> JsonPointer<S, C>

Creates a new JsonPointer from the given reference tokens.

fn get<'json>(&self, val: &'json Value) -> Result<&'json Value, IndexError>

Attempts to get a reference to a value from the given JSON value, returning an error if it can't be found.

fn get_mut<'json>(
    &self,
    val: &'json mut Value
) -> Result<&'json mut Value, IndexError>

Attempts to get a mutable reference to a value from the given JSON value, returning an error if it can't be found.

fn get_owned(&self, val: Value) -> Result<Value, IndexError>

Attempts to get an owned value from the given JSON value, returning an error if it can't be found.

impl<S: AsRef<str>> JsonPointer<S, Vec<S>>

fn push(&mut self, component: S)

Adds a component to the JSON pointer.

fn pop(&mut self) -> Option<S>

Removes and returns the last component from the JSON pointer.

Trait Implementations

impl FromStr for JsonPointer<String, Vec<String>>

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.
