Enum JsonValue 

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

A native Rust representation of any valid JSON value.

This enum is used by the stringify functions to serialize Rust data into a JSON string.

Variants

Null

Represents a JSON null.

Boolean(bool)

Represents a JSON true or false.

Number(f64)

Represents a JSON number (stored as f64).

String(String)

Represents a JSON string.

Array(Vec<JsonValue>)

Represents a JSON array (list).

Object(HashMap<String, JsonValue>)

Represents a JSON object (map).

Implementations

impl JsonValue

pub fn stringify(&self) -> String

Serializes the JsonValue into a compact, minified JSON string.

Examples

use rill_json::JsonValue;
let val = JsonValue::Number(123.0);
assert_eq!(val.stringify(), "123");

pub fn stringify_pretty(&self) -> String

Serializes the JsonValue into a human-readable, indented JSON string (“pretty-print”).

Examples

use rill_json::JsonValue;
use std::collections::HashMap;

let mut obj = HashMap::new();
obj.insert("key".to_string(), JsonValue::String("value".to_string()));
let val = JsonValue::Object(obj);

let pretty = val.stringify_pretty();
assert!(pretty.starts_with("{\n"));
assert!(pretty.contains("\n  \"key\": \"value\"\n"));
assert!(pretty.ends_with("\n}"));

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.
