A Fast osu! pp calculator web api written in Rust

It is also the PP server of Peace.

Pure-Rust pp calculator based on peace-performance and rosu-pp.

Features

• Common:
  • request with you like: beatmap md5, beatmap id, beatmapset id + file name
  • beatmap cache
  • preload beatmaps (WARING: May cause insufficient memory, if the number of maps is large enough)
  • calculate beatmap MD5
  • auto request, download beatmap from osu!api
  • raw pp info: aim, spd, acc, str.
  • acc list: 95, 98, 99, 100 (request with &acc_list=1)
  • Oppai? Or a custom algorithm
  • auto-pp-recalculate (peace)
    • If pp calculation fails (such as restarting pp-server), just save task to redis in the format of "calc:{table(mode)}:{score_id}:{player_id}":"md5=xxx&mods=xx&mode=xx&n300=xx". pp-server will auto recalculate these tasks, and notify peace to update the stats of these players. .
  • pp calculate:
    • osu!Standard
    • Catch the beat
    • Taiko
    • Mainia
• (Default Enabled) feature with_peace:
  • beatmap database (needs setup with Peace)
  • auto pp recalculate
  • How to enable?
    • Cargo.toml features Set default = ["with_peace"]
    • Will run as a pp server of Peace
  • How to disable?
    • Set features default = ["peace-objects/no_database"]
    • Not use peace database, run pp-server independently.

Best performance (Fastest, but lower accuracy)

Set Cargo.toml

peace-performance = { ... }

to

peace-performance = { ..., feature = "no_sliders_no_leniency" }

Note

This pp-server requires all .osu files use file MD5 as the name.

• Rename .osu files to file md5:

  • If you want pp server auto recalculate all .osu files MD5 name before started, set recalculate_osu_file_md5 = true in config/pp-server/default.toml
  • Or manual run this python script rename_osu_files.py in project (python3.8+).
  • If its Debug compile, python will more faster than Rust.

• Effect

  • Calculating
  • 
  • After
  • 

Setup

1. Set your .osu files dir path in config/pp-server/default.toml
2. Will let the .osu files name be the md5 of the file
3. Set your osu!api keys in *.toml (if enabled feature peace, set it on your database)

Debug

cargo run

Release

cargo run --release
