Enum JsonValue 

pub enum JsonValue {
    Null,
    Boolean(bool),
    Number(f64),
    String(String),
    Array(Vec<JsonValue>),
    Object(HashMap<String, JsonValue>),
}

A JSON value

Variants

Null

A null value

Boolean(bool)

A boolean value

Number(f64)

A number value, which is a decimal (f64 in Rust)

String(String)

A string value

Array(Vec<JsonValue>)

An array value

Object(HashMap<String, JsonValue>)

An object value

Implementations

impl JsonValue

pub fn build_object(input: Vec<(String, JsonValue)>) -> Self

Creates an object instance from a list of String,JsonValue (key,value) tuples.

pub fn stringify(&self) -> String

Works same as the stringify method for objects in JavaScript

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

If the value is a boolean, returns Some(that boolean), else None

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

If the value is a number, returns Some(that number), else None

pub fn get_string(&self) -> Option<String>

If the value is a string, returns Some(that string), else None. Note that the string is cloned, so the original value is not borrowed

pub fn get_array(&self) -> Vec<JsonValue>

If the value is a array, returns a clone of that array; else returns an empty array

pub fn get_object(&self) -> Option<HashMap<String, JsonValue>>

If the value is an object, returns Some(a clone of that object’s inner string -> JsonValue hashmap); else returns None

pub fn is_null(&self) -> bool

Returns TRUE if and only if the value is null

pub fn get_integer(&self) -> Option<u64>

Returns Some(a u64 integer) if the value can be parsed as such; else None

pub fn get_json_date(&self) -> Option<JsonDate>

Returns Some(a JsonDate) if the value can be parsed as such; else None. Note that this only works with String values that approximate the expected format. (See JsonDate)

pub fn parse(input: Vec<u8>) -> Option<JsonValue>

Parses a JsonValue from an input array of bytes

Trait Implementations

impl Clone for JsonValue

fn clone(&self) -> JsonValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsonValue

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

Formats the value using the given formatter.
