Enum glib::OptionArg [−][src]
#[non_exhaustive] pub enum OptionArg { None, String, Int, Callback, Filename, StringArray, FilenameArray, Double, Int64, // some variants omitted }
Expand description
The OptionArg
enum values determine which type of extra argument the
options expect to find. If an option expects an extra argument, it can
be specified in several ways; with a short option: -x arg
, with a long
option: --name arg
or combined in a single argument: --name=arg
.
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
No extra argument. This is useful for simple flags.
The option takes a UTF-8 string argument.
The option takes an integer argument.
The option provides a callback (of type
GOptionArgFunc
) to parse the extra argument.
The option takes a filename as argument, which will be in the GLib filename encoding rather than UTF-8.
The option takes a string argument, multiple uses of the option are collected into an array of strings.
The option takes a filename as argument, multiple uses of the option are collected into an array of strings.
The option takes a double argument. The argument can be formatted either for the user’s locale or for the “C” locale. Since 2.12
The option takes a 64-bit integer. Like
Int
but for larger numbers. The number can be in
decimal base, or in hexadecimal (when prefixed with 0x
, for
example, 0xffffffff
). Since 2.12
