Ohos-sys

This crate provides Raw FFI bindings to the native API of OpenHarmonyOS (target_env = "ohos"). Each module corresponds to one OpenHarmony API feature, and is gated behind a cargo feature. If you are an application developer, you probably do not want to use this crate directly, and instead want to use a higher-level API built on top of this crate.

Note: There are currently still quite a few missing bindings, which will slowly be added.
