//! A configurable source of time. //! //! This module provides an API to get the current instant in such a way that //! the source of time may be configured. This allows mocking out the source of //! time in tests. //! //! The [`now`][n] function returns the current [`Instant`]. By default, it delegates //! to [`Instant::now`]. //! //! The source of time used by [`now`][n] can be configured by implementing the //! [`Now`] trait and passing an instance to [`with_default`]. //! //! [n]: fn.now.html //! [`Now`]: trait.Now.html //! [`Instant`]: https://doc.rust-lang.org/std/time/struct.Instant.html //! [`Instant::now`]: https://doc.rust-lang.org/std/time/struct.Instant.html#method.now //! [`with_default`]: fn.with_default.html mod clock; mod now; pub use self::clock::{now, set_default, with_default, Clock, DefaultGuard}; pub use self::now::Now;
