pub fn lua_to_json(_lua: &Lua, val: Value) -> Result<Value, Error>Expand description
Convert a Lua value to a serde_json::Value.
Round-trips with json_to_lua and std.json.encode (mlua-batteries).
Lua nil maps to JSON null. Unsupported types (functions, userdata
other than null) yield an error so that callers do not silently emit
malformed JSON.
