//! A no_std compatible time point and duration library.
//!
//! # Duration
//!
//! The [`Duration`] type is inspired by [`smoltcp::time::Duration`] and
//! [`embassy_time::Duration`] but allows for negative duration values as well.
//!
//! [`smoltcp::time::Duration`]: https://docs.rs/smoltcp/0.10.0/smoltcp/time/struct.Duration.html
//! [`embassy_time::Duration`]: https://docs.embassy.dev/embassy-time/git/default/struct.Duration.html
//!
//! # Time points
//!
//! The [`TimePoint`] type is keyed on which `Clock` it originates from. This catches errors such
//! as accidentally comparing time points from different clocks.
//!
//! # Features
//!
//!   * `std` - enabled by default.
//!
