Implementations

impl Json

pub fn deserialize(text: impl AsRef<str>) -> Result<Json, Error>

Deserializes the given string into a Json object

Configuration used

max_depth = u32::MAX

recover_from_errors = false

pub fn deserialize_with_config( text: impl AsRef<str>, conf: JsonConfig, ) -> Result<Json, Error>

Deserializes the given string into a Json object using the given JsonConfig

pub fn serialize(&self, out: &mut dyn Write) -> Result

Serializes the JSON object into a fmt::Write

pub fn get(&self, key: impl AsRef<str>) -> Option<&Json>

Attempts to get a value of the given json object. If the json enum is not an Object variant, or if it doesn’t contain the key, returns None

pub fn get_mut(&mut self, key: impl AsRef<str>) -> Option<&mut Json>

Same as get, but with a mutable reference

pub fn nth(&self, i: usize) -> Option<&Json>

Attempts to get a value of the given json array. If the json enum is not an Array variant, or if it doesn’t contain the key, returns None

pub fn nth_mut(&mut self, i: usize) -> Option<&mut Json>

Same as nth, but with a mutable reference

pub fn number(&self) -> Option<f64>

Attempts to get the inner f64 of the json object, if it is a Number variant

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

Attempts to get the inner String of the json object, if it is a String variant

pub fn object(&self) -> Option<&Map<Box<str>, Json>>

Attempts to get the inner Object of the json object, if it is an Object variant

pub fn array(&self) -> Option<&[Json]>

Attempts to get the inner Array of the json object, if it is an Array variant

pub fn boolean(&self) -> Option<bool>

Attempts to get the inner boolean value of the json object, if it is a True or False variant

pub fn is_null(&self) -> bool

Returns true if the json is a Nil variant

Trait Implementations

impl<'a> From<&'a str> for Json

fn from(value: &'a str) -> Self

Converts to this type from the input type.

impl From<Box<str>> for Json

fn from(value: Box<str>) -> Self

Converts to this type from the input type.

impl From<HashMap<Box<str>, Json>> for Json

fn from(value: Map<Box<str>, Json>) -> Self

Converts to this type from the input type.

impl From<Vec<Json>> for Json

fn from(value: Vec<Json>) -> Self

Converts to this type from the input type.

impl From<bool> for Json

fn from(value: bool) -> Self

Converts to this type from the input type.

impl From<f32> for Json

fn from(value: f32) -> Self

Converts to this type from the input type.

impl From<f64> for Json

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<i16> for Json

fn from(value: i16) -> Self

Converts to this type from the input type.

impl PartialEq for Json

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