Enum JValue 

pub enum JValue {
    Null,
    Bool(bool),
    Number(f64),
    String(Rc<str>),
    Array(Rc<Vec<JValue>>),
    Object(Rc<IndexMap<String, JValue>>),
    Undefined,
    Lambda {
        lambda_id: Rc<str>,
        params: Rc<Vec<String>>,
        name: Option<Rc<str>>,
        signature: Option<Rc<str>>,
    },
    Builtin {
        name: Rc<str>,
    },
    Regex {
        pattern: Rc<str>,
        flags: Rc<str>,
    },
}

A JSON-like value with O(1) clone semantics via Rc-wrapping.

Standard JSON types (Array, Object, String) are wrapped in Rc for cheap cloning. Internal types (Undefined, Lambda, Builtin, Regex) are first-class variants instead of tagged objects with hash-map lookups.

Get a mutable reference to the inner IndexMap, cloning if shared (Rc::make_mut).

pub fn as_rc_str(&self) -> Option<&Rc<str>>

Get a reference to the Rc for the string variant.

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

Index into an object by key.

pub fn get_index(&self, index: usize) -> Option<&JValue>

Index into an array by position.

impl JValue

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

Serialize to a JSON string.

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

Serialize to a pretty-printed JSON string.

pub fn from_json_str(s: &str) -> Result<JValue, Error>

Parse a JSON string into a JValue (single-pass, no intermediate serde_json::Value).

When the simd feature is enabled, uses simd-json for 2-4x faster parsing on CPUs with SIMD support (SSE4.2/AVX2/NEON). Falls back to serde_json otherwise.

Trait Implementations

impl Clone for JValue

fn clone(&self) -> JValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JValue

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for JValue

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

Formats the value using the given formatter.
