//! A crate to make time measurements that focuses on speed. //! //! This crate is a partial replacement for the `Time` and `Duration` structures from the //! standard library, with the following differences: //! //! * Speed is privileged over accuracy. In particular, `CLOCK_MONOTONIC_COARSE` is used to //! retrieve the clock value on Linux systems, and transformations avoid operations that can be //! slow on non-Intel systems. //! * The number of system calls can be kept to a minimum. The "most recent timestamp" is //! always kept in memory. It can be read with just a load operation, and can be updated only as //! frequently as necessary. //! //! # Installation //! //! `coarsetime` is available on [crates.io](https://crates.io/crates/coarsetime) and works on //! Rust stable, beta, and nightly. //! //! Windows and Unix-like systems are supported. //! //! Available features: //! //! * `nightly`: optimizes for rust-nightly #![allow(clippy::trivially_copy_pass_by_ref)] #![cfg_attr(feature = "nightly", feature(test))] #[macro_use] extern crate lazy_static; pub use self::clock::*; pub use self::duration::*; pub use self::instant::*; pub use self::updater::*; mod clock; mod duration; mod helpers; mod instant; mod updater; #[cfg(test)] mod tests;
