pub(super) fn stable_repr(v: &Value) -> StringExpand description
Produce a deterministic string representation of a serde_json::Value
suitable for stable hashing.
Object keys are sorted recursively so that {"b":2,"a":1} and
{"a":1,"b":2} produce identical output. Array element order is
preserved. Recursion is capped at MAX_REPR_DEPTH to prevent
stack overflow on adversarially nested inputs; values beyond that depth
are replaced with the sentinel "...", which means two deeply-nested
values that differ only below depth 16 will hash identically.
The output is not valid JSON — it is intentionally compact and only used as a pre-image for FNV-1a; never parsed or returned to callers.
