Source
Available on crate feature unstable only.
Expand description

§Low-level clock control

This module provides experimental low-level clock control functionality. These functions can render the device temporarily unusable. Use with caution.

§Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.
