3//! # What's the difference between these traits and the `timer::CountDown` trait?
4//!
5//! The `Timer` trait provides a *non-blocking* timer abstraction and it's meant to be used to build
6//! higher level abstractions like I/O operations with timeouts. OTOH, these delays traits only
7//! provide *blocking* functionality. Note that you can also use the `timer::CountDown` trait to
8//! implement blocking delays.

10/// Millisecond delay
11///
12/// `UXX` denotes the range type of the delay time. `UXX` can be `u8`, `u16`, etc. A single type can
13/// implement this trait for different types of `UXX`.
14pub trait DelayMs<UXX> {
15 /// Pauses execution for `ms` milliseconds
16 fn delay_ms(&mut self, ms: UXX);
