| 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. |
