osu-file-parser

---

A crate to parse an osu! beatmap file.

How to use

use osu_file_parser::*;

let osu_file_str = include_str!("./tests/osu_files/files/acid_rain.osu");
// parse the .osu file
let mut osu_file = osu_file_str.parse::<OsuFile>().unwrap();

let osb_str = include_str!("./tests/osu_files/files/acid_rain.osb");
// .osb file can also be parsed and appended to the `OsuFile` instance
osu_file.append_osb(osb_str).unwrap();

// you can use `assert_eq_osu_str` to assert that the parsed .osu file is equal to the original .osu file
assert_eq_osu_str(&osu_file.to_string(), osu_file_str);
assert_eq_osu_str(&osu_file.osb_to_string().unwrap(), osb_str);

General information

Alternative traits

• Most of the types in the crate uses the VersionedToString, VersionedFromStr and VersionedDefault traits as replacements for the Display, FromStr and Default traits.
• Those traits take an extra version parameter to choose what version output to use.
• If the type doesn't exist in certain versions, the output will be None.

Errors

• Structs that takes lines of string as input can return errors containing information of where the error occurred and what the error was.
• The error type is wrapped in Error in those cases.
• Error has methods that tells you where the error happened in the input string and what the error was.
