gd32e2-hal 0.15.2

//! Typed units for frequencies and durations, aliased from `fugit`.
//!
//! The units themselves come from [`fugit`], which keeps rates and durations
//! apart as distinct kinds and converts between scales at compile time. This
//! module names its `u32` instances, so signatures stay short and the dependency
//! is pinned in one place; `u64` is not aliased, the core being 32-bit.
//!
//! The scale lives in the type and costs nothing at runtime, so a value crosses
//! between units by conversion rather than by arithmetic on a bare number.
//!
//! The generic [`Duration`] and [`Rate`] are re-exported for signatures that
//! stay open to any scale, as are the suffix traits: [`ExtU32`] for durations
//! and [`RateExtU32`] for frequencies. The whole crate is re-exported too, so
//! `Instant`, the tick-based `TimerDuration` and the `u64` widths are reachable
//! without adding a matching dependency downstream.
//!
//! ```ignore
//! use gd32e2_hal::time::ExtU32;
//! let period = 5.secs();
//! ```
