Enum JsonValue 

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

A JSON value. Objects keep their members in insertion order (a Vec of pairs, not a map) so a serialized packet is byte-stable.

Variants

Null

null.

Bool(bool)

true / false.

Number(String)

A number, kept as its literal text (so integer/decimal formatting round-trips exactly).

String(String)

A string.

Array(Vec<JsonValue>)

An ordered array.

Object(Vec<(String, JsonValue)>)

An ordered object: (key, value) members in insertion order.

Implementations

impl JsonValue

pub fn str(s: impl Into<String>) -> JsonValue

Construct a string value.

pub fn uint(n: u64) -> JsonValue

Construct a number value from a u64.

pub fn get(&self, key: &str) -> Option<&JsonValue>

Look up a member of an object by key (first match), or None.

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

The string contents if this is a String, else None.

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.

impl PartialEq for JsonValue

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