Implementations

impl Value

pub fn is_truthy(&self) -> bool

jq-style truthiness: only false and null are falsy.

pub fn type_name(&self) -> &'static str

The type name, as reported by the type builtin.

pub fn as_f64(&self) -> Option<f64>

Numeric coercion to f64 for arithmetic and comparison.

pub fn order(&self, other: &Value) -> Ordering

Total order across types (jq’s ordering: null < bool < number < string < array < object).

pub fn value_eq(&self, other: &Value) -> bool

Structural equality consistent with Value::order.

pub fn to_raw_string(&self) -> String

Render as a raw scalar for query output (no surrounding quotes on strings). Composite values are rendered as JSON.

pub fn to_json(&self) -> String

Render as compact JSON.

pub fn to_json5(&self) -> String

Render as compact JSON in the JSON5 spelling: non-finite floats keep their Infinity / -Infinity / NaN literals instead of degrading to null. This is what the JSONC/JSON5-family emitters use, so converting or querying a JSON5 source with a non-finite number preserves it; strict JSON must use Value::to_json (which, like JSON.stringify, encodes one as null).

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl<T: Into<Value> + Clone> From<&[T]> for Value

fn from(input: &[T]) -> Self
