Function diff_shadow_mismatch_json 

pub fn diff_shadow_mismatch_json(
    cached: &Value,
    source: &Value,
) -> MismatchJsonDiff

The built-in difference computation over two JSON values.

Objects recurse over the union of their member names in UTF-16 code-unit order, and a member present on one side only is reported at its pointer with that side. Arrays of equal length recurse by index; arrays of different length are reported once at their own pointer. Any other differing pair, roots of different kinds included, is reported at its pointer with both sides, and a differing pair of containers at SHADOW_MISMATCH_MAX_DEPTH reference tokens is reported whole without descending. Numbers compare by value as doubles, so 1 and 1.0 are equal. Entries keep walk order and are cut at SHADOW_MISMATCH_MAX_ENTRIES; count is the uncut total. Each pointer is clamped to SHADOW_MISMATCH_PATH_MAX_BYTES, and a side whose JSON exceeds SHADOW_MISMATCH_SIDE_MAX_BYTES becomes its clamped JSON text as a string.
