+//! Delays

+//! # What's the difference between these traits and the `Timer` trait?
+//!
+//! The `Timer` trait provides a *non-blocking* timer abstraction and it's meant to be used to build
+//! higher level abstractions like I/O operations with timeouts. OTOH, these delays traits only
+//! provide blocking functionality. Note that you can also use the `Timer` trait to implement
+//! blocking delays.
+
+/// Microsecond delay
+///
+/// `UXX` denotes the range type of the delay time. `UXX` can be `u8`, `u16`, etc. A single type can
+/// implement this trait for different types of `UXX`.
+pub trait DelayMs<UXX> {
+    /// Pauses execution for `ms` milliseconds
+    fn delay_ms(&mut self, ms: UXX);
