}
Beatmap is a single difficulty within a BeatmapSet. Mirrors the beatmaps table. MD5Hash is the change-detection key: any edit to the .osu file changes it, which is how we know a difficulty needs its Skills recomputed.
type BeatmapSet ¶
type BeatmapSet struct {
BeatmapSetID int32 `db:"beatmap_set_id"`
SongTitle string `db:"song_title"`
SongTitleUni string `db:"song_title_uni"`
ArtistName string `db:"artist_name"`
ArtistNameUni string `db:"artist_name_uni"`
CreatorName string `db:"creator_name"`
SongSource string `db:"song_source"`
SongTags string `db:"song_tags"`
}
BeatmapSet is one mapset — a group of Beatmap difficulties sharing the same song. Mirrors the beatmapsets table 1:1.
type MD5Hash ¶
type MD5Hash [16]byte
MD5Hash stores an MD5 digest as raw bytes rather than a 32-character hex string — halves storage per row (16 bytes vs 32) and makes index/equality comparisons operate on raw bytes instead of ASCII text. Comparable with == since it's a fixed-size array.
func MustParseMD5Hash ¶
MustParseMD5Hash is ParseMD5Hash but panics on error — use only where the input is already known-good (e.g. constants in tests).
func ParseMD5Hash ¶
ParseMD5Hash decodes a 32-character hex string (as found in osu!.db / osu.DatabaseBeatmap.MD5Hash) into an MD5Hash.
type SkillCache ¶
type SkillCache struct {
BeatmapID int32 `db:"beatmap_id"`
Mods int32 `db:"mods"`
MD5Hash MD5Hash `db:"md5_hash"`
Stamina float64 `db:"stamina"`
Tenacity float64 `db:"tenacity"`
Agility float64 `db:"agility"`
Precision float64 `db:"precision"`
Reading float64 `db:"reading"`
Memory float64 `db:"memory"`
Accuracy float64 `db:"accuracy"`
Reaction float64 `db:"reaction"`
}
SkillCache is one (Beatmap, mod combination) pair's computed Skills. MD5Hash is copied from the owning Beatmap at compute time so staleness can be checked without a join.
