The ArceOS Standard Library

The ArceOS Standard Library is a mini-std library, with an interface similar to rust [std], but calling the functions directly in ArceOS modules, instead of using libc and system calls.

These features are exactly the same as those in [ax-feat], they are used to provide users with the selection of features in ax-feat, without import [ax-feat] additionally:
