Enum JsonValue 

pub enum JsonValue {
    Null,
    Boolean(bool),
    Number(JsonNumber),
    String(String),
    Array(Vec<JsonValue>),
    Object(BTreeMap<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(JsonNumber)

Represents a JSON number.

String(String)

Represents a JSON string.

Array(Vec<JsonValue>)

Represents a JSON array (list).

Object(BTreeMap<String, JsonValue>)

Represents a JSON object (map). We use BTreeMap to guarantee deterministic (alphabetical) key order during serialization.

Implementations

impl JsonValue

pub fn parse(input: &str) -> Result<JsonValue, ParseError>

Parses a JSON string into a JsonValue.

This function builds an in-memory JsonValue from the input string. For large inputs, using the parse_streaming iterator is more memory-efficient.

Errors

Returns a ParseError if the JSON is invalid, empty, or has trailing tokens.

impl JsonValue

pub fn stringify(&self) -> Result<String, Error>

Serializes the JsonValue into a compact, minified JSON string.

Errors

Returns fmt::Error if the value contains f64::NAN or f64::INFINITY.

pub fn stringify_pretty(&self) -> Result<String, Error>

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

Errors

Returns fmt::Error if the value contains f64::NAN or f64::INFINITY.

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.
