function write_pretty(out: mut &String, v: &JsonValue) -> void;

Function	Notes
stringify(v)	Compact — no whitespace between tokens.
stringify_pretty(v)	Two-space indent, one entry per line.
write_value(out, v)	Append compact output to a string you own.
write_pretty(out, v)	Append pretty output.

The write_* forms exist so several values can be concatenated into one buffer without intermediate allocations. Empty objects and arrays stay on a single line even in pretty mode.

String output escapes per the spec: UTF-8 bytes outside the ASCII control range pass through, and bytes below 0x20 are emitted as \uXXXX. Floats are written with the round-trip formatter, so a parsed 0.1 serializes as 0.1.

The serializer mirrors the parser's depth cap, so a parsed tree always round-trips; only a programmatically built tree deeper than 256 is bounded, and that is there to stop unbounded recursion on adversarial input.
