Modules

BpmChange
Chartkey	Represents an Etterna chartkey
DifficultyParseError
FastestComboInfo	Information about a combo found by `find_fastest_note_subset`
FullJudgements	Judgement data, including mines and holds
Judge	Specification of a judgement level
MatchingScorer	Scoring system that assigns hits to notes by trying to find the optimal mapping between the two, instead of naively mapping notes to hits as they come (`crate::NaiveScorer`).
NaiveScorer	Replica of the naive straightforward scoring system as it’s usually implemented in mania rhythm games. It maps hits to notes linearly.
NoteAndHitSeconds	No guaranteess of any sorts about ordering or contents in general
NoteRow
Rate	Represents an Etterna chart rate (music speed).
RateParseError
Scorekey	Represents an Etterna scorekey
ScoringResult	Result of evaluating a `ScoringSystem` on a list of notes and hits (`ScoringSystem::evaluate`)
SkillTimeline	Representation of a player’s ratings over time. See `skill_timeline`
Skillsets7	Skillset information, excluding overall
Skillsets8	Skillset information, excluding overall
TapJudgements	Judgement data, only the basic tap judgements
TimingInfo
UserRank	Global ranks in each skillset category
Wife2	2nd revision of Etterna’s Wife scoring system
Wife3	3rd revision of Etterna’s Wife scoring system
Wifescore	Wifescore struct. Guaranteed to be a valid value, i.e. <= 100% and not NaN (may be negative infinity though)

Difficulty	Chart difficulty enum
Hit	Represents a player hit of a single note
NoteType	Type of a note
ScrollDirection
Skillset7	Skillsets enum, excluding overall
Skillset8	Skillsets enum, including overall

TapJudgement

J1	Removed from Etterna in 0.69.0
J2	Removed from Etterna in 0.69.0
J3	Removed from Etterna in 0.69.0
J4	Default judge for official scoring
J5	Used by some as their go-to judge
J6	Sometimes used for accuracy training
J7	Half the timing window of J4. Common for accuracy training
J8	Half the timing window of J6
J9	Also called “Justice”. Originally added to the game as a joke

ScoringSystem	Trait for a scorer that operates on a single column and evaluates all hits on that column. It needs the entire list of hits available to it at the same time
SimpleReplay
Wife	Trait that abstracts over wifescore algorithm - the algorithm that turns a hit deviation into a score percent

calculate_player_overall	Calculate a player’s overall rating from the player’s seven individual skillset ratings.
calculate_player_skillset_rating	Calculate a player’s skillset rating from the individual scores’ skillset ratings
calculate_player_skillset_rating_pre_070	This is the pre-0.70 variant of `calculate_player_skillset_rating`.
calculate_score_overall	Calculate a score’s overall difficulty from the score’s seven individual skillsets.
find_fastest_combo_in_score	Find the fastest combo within the score. It searched only for combos whose lengths lie inside `min_num_notes..=max_num_notes`.
find_fastest_note_subset	This function finds the fastest note subset (where the number of notes in the subset is in `min_num_notes..=max_num_notes`). The function operates on a single lane only!
find_fastest_note_subset_wife_pts	This function finds the “best” note subset (where the number of notes in the subset is in `min_num_notes..=max_num_notes`). The function operates on a single lane only!
rescore	Calculates a wifescore from a list of notes per column and hits per column, plus the mine hits and hold drops. The wifescore algorithm and scoring algorithm used can be chosen via the generic parameters.
rescore_from_note_hits	Calculate a wifescore from a replay’s note hits, mine hits and hold drops.
skill_timeline	Deprecated
wife2	Utility function to calculate a Wife2 score for a single hit deviation
wife3	Utility function to calculate a Wife3 score for a single hit deviation
