lib.gvariant.mkValue

The following is the current implementation of this function.

mkValue =
    v:
    if builtins.isBool v then
      mkBoolean v
    else if builtins.isFloat v then
      mkDouble v
    else if builtins.isString v then
      mkString v
    else if builtins.isList v then
      mkArray v
    else if isGVariant v then
      v
    else if builtins.isInt v then
      let
        validConstructors = builtins.filter (
          { min, max, ... }: (min == null || min <= v) && (max == null || v <= max)
        ) intConstructors;
      in
      throw ''
        The GVariant type for number “${builtins.toString v}” is unclear.
        Please wrap the value with one of the following, depending on the value type in GSettings schema:

        ${lib.concatMapStringsSep "\n" (
          { name, type, ... }: "- `lib.gvariant.${name}` for `${type}`"
        ) validConstructors}
      ''
    else if builtins.isAttrs v then
      throw "Cannot construct GVariant value from an attribute set. If you want to construct a dictionary, you will need to create an array containing items constructed with `lib.gvariant.mkDictionaryEntry`."
    else
      throw "The GVariant type of “${builtins.typeOf v}” can't be inferred.";
