Module json 

JSON helpers shared by the reducer, the expander and the theme resolver: the JavaScript number model (one double; integral values print without a fraction) and a canonical form for byte-for-byte fixture comparisons.

Functions

as_f64

Every number as f64.

as_obj

value as an object, if it is one.

canonical

The canonical form two JSON documents are compared in: numbers through number (so 2.0 == 2), -0 == 0, objects and arrays recursively.

clone_value

A deep clone through Value (the TS JSON.parse(JSON.stringify(x))).

equal

true when both documents are the same in canonical form.

number

A JS-style number: integral doubles become JSON integers (1, not 1.0), everything else stays a float. NaN/±∞ become null like JSON.stringify.

number_to_string

JavaScript’s String(number) (ECMAScript Number::toString): the shortest round-trip digits, plain from 1e-6 up to 1e21, exponent form (1e-7, 1e+21) outside; -0 → 0, NaN, Infinity.

obj

The empty object.

str_of

The object’s key k as a &str.

strict_eq

JavaScript === over JSON values (numbers by value, no coercion).

to_js_string

JavaScript’s String(value) for the scalar values a template may interpolate: strings verbatim, numbers through number_to_string, booleans true/false, null, arrays comma-joined, objects [object Object].

to_number

JavaScript’s Number(value) || 0.
