[−][src]Crate xvii
XVII
...Pronounced any way you like--including "seventeen."
This library provides parsing and formatting for Roman numerals. According to my (probably extremely suspect) benchmarks, this is the best-performing library of its kind available on crates.io (you know, as of St. Patrick's Day, 2017 when I did the tests), so you should definitely employ it in your high-availability NAAS (numerals-as-a-service) project.
(Seriously, though, read the license--no warranties implied!)
let seventeen: Roman = "XVII".parse().unwrap(); assert_eq!(17, seventeen.value()); assert_eq!("XVII", seventeen.to_string()); let seventeen = Roman::new(17).unwrap(); assert_eq!(17, seventeen.value()); assert_eq!("XVII", seventeen.to_string());
no_std
support
no_std
mode is supported if crate is built without std
feature (enabled by default).
I.e. you need to turn off default features to build xvii
without std:
xvii = { version = "...", default-features = false }
