//! OS-specific functionality.
/// ArceOS-specific definitions.
///
/// `api` re-exports the public ArceOS API surface. Prefer this entry for
/// ArceOS-specific operations that do not have a std-like wrapper.
///
/// `modules` re-exports lower-level ArceOS modules as an escape hatch for
/// complex systems such as Axvisor. Ordinary applications should prefer
/// `ax_std::{fs, io, thread, sync, time, net}`.
