Where can I find the Locale Information Constants in Rust's winapi crate?

Question

Are the Windows NLS API Locale Information Constants available anywhere in the winapi-rs crate or elsewhere in the Rust ecosystem?

I need to call GetLocaleInformationEx from Rust and have found it available in the um::winnls module of the winapi-rs crate (here).

The LCType input is a Locale Information Constant -- and I have not been able to find these defined anywhere in the crate.

As a workaround, I have looked up the numerical values and hard-coded them, but I have a nagging feeling that I am missing something.

This is a late answer, but since other people can have this issue as well, so I'll still write my solution:

While the winapi crate doesn't contain all locale information constants, the windows-sys crate does.

On this Microsoft site there is a list of all available Locale information constants. These are also available as constants in windows_sys::Win32::Globalization, see here.

If you want to use winapi instead of windows-sys, I'd advice to just look up the value of the respective locale there and define your own constant in your Rust code.
