Rust chrono now
WebbThis program prints the current date and time in the system and UTC timezone. It uses the Chrono library to access current timestamp-related information. Let’s create a new rust project using the cargo command. cargo new dateapp Next, Change the directory to dateapp cd dateapp Add the Chrono dependency in cargo.toml file WebbChrono has to support the system-local time zone ( Local::now () etc). That system-local time zone has to match what C localtime* etc. will return. It can look obvious that the solution is to bump the time-rs dependency to 0.3, but the very reason that time-rs 0.1 is required in the first place was to determine the local time zone.

WebbRust Cookbook 是 Rust 官方图书的中文翻译版，由一系列简单程序示例构成，展示了 Rust 实际开发场景的良好实践。 WebbRust provides a "SystemTime" type but really the only useful thing you can do with this is display it or get a Duration from it. Right now I have a simple proof of concept API that uses a SystemTime to get a Unix timestamp and exposed this to the language.

It aims to be a feature-complete superset of the time library. In particular, Chrono strictly adheres to ISO 8601. Chrono is timezone-aware by default, with separate timezone-naive types. Chrono is space-optimal and (while not being the primary goal) reasonably efficient. There were several previous attempts to ...
WebbThe borrow checker is the kingpin here. it seems like a very simple language compare to rust. And this is its primary purpose. The Zig Zen is all about explicit intent, no hidden behavior, and minimizing programmer overhead, and the compiler’s role is to assist you in finding common footguns like undefined behavior. Webb25 nov. 2024 · let start = time::now_utc () + Duration::days (-180); Then I get the modified time. let metadata = match fs::metadata (path) { Err (_why) => continue, Ok (f) => f,}; let mtime = metadata.modified (); How do I see if mtime is greater than start? Any help and corrections appreciated and thanks. 1 Like hyousef November 25, 2024, 6:41pm 2
