//! Delays //! //! # What's the difference between these traits and the `timer::CountDown` 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::CountDown` trait to //! implement blocking delays. /// Millisecond 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); } /// 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 DelayUs<UXX> { /// Pauses execution for `us` microseconds fn delay_us(&mut self, us: UXX); }
