--- The `cjson.safe` module behaves identically to the `cjson` module, except when
--- errors are encountered during JSON conversion. On error, the `cjson.safe.encode`
--- and `cjson.safe.decode` functions will return `nil` followed by the error message.

--- @see cjson

---@class cjson.safe : cjson
local cjson_safe = {}
--- unserialize a json string to a lua value
---
--- Returns `nil` and an error string when the input cannot be decoded.
---
--- ```lua
--- local value, err = cjson_safe.decode(some_json_string)
--- ```
---@param json string
---@return any? decoded
---@return string? error
function cjson_safe.decode(json) end
--- serialize a lua value to a json string
