| //! Timestamps for files in Rust |
| //! |
| //! This library provides platform-agnostic inspection of the various timestamps |
| //! present in the standard `fs::Metadata` structure. |
| //! |
| //! # Installation |
| //! |
| //! Add this to your `Cargo.toml`: |
| //! |
| //! ```toml |
| //! [dependencies] |
| //! filetime = "0.2" |
| //! ``` |
| //! |
| //! # Usage |
| //! |
| //! ```no_run |
| //! use std::fs; |
| //! use filetime::FileTime; |
| //! |
| //! let metadata = fs::metadata("foo.txt").unwrap(); |
| //! |
| //! let mtime = FileTime::from_last_modification_time(&metadata); |
| //! println!("{}", mtime); |
| //! |
| //! let atime = FileTime::from_last_access_time(&metadata); |
| //! assert!(mtime < atime); |
| //! |
| //! // Inspect values that can be interpreted across platforms |
| //! println!("{}", mtime.unix_seconds()); |
| //! println!("{}", mtime.nanoseconds()); |
| //! |
| //! // Print the platform-specific value of seconds |
| //! println!("{}", mtime.seconds()); |
| //! ``` |
