Struct ManiaPerformance 

pub struct ManiaPerformance<'map> { /* private fields */ }

Performance calculator on osu!mania maps.

Implementations

impl<'map> ManiaPerformance<'map>

pub fn new(map_or_attrs: impl IntoModePerformance<'map, Mania>) -> Self

Create a new performance calculator for osu!mania maps.

The argument map_or_attrs must be either

• previously calculated attributes (ManiaDifficultyAttributes or ManiaPerformanceAttributes)
• a Beatmap (by reference or value)

If a map is given, difficulty attributes will need to be calculated internally which is a costly operation. Hence, passing attributes should be prefered.

However, when passing previously calculated attributes, make sure they have been calculated for the same map and Difficulty settings. Otherwise, the final attributes will be incorrect.

pub fn try_new(map_or_attrs: impl IntoPerformance<'map>) -> Option<Self>

Try to create a new performance calculator for osu!mania maps.

Returns None if map_or_attrs does not belong to osu!mania i.e. a DifficultyAttributes or PerformanceAttributes of a different mode.

See ManiaPerformance::new for more information.

pub fn mods(self, mods: impl Into<GameMods>) -> Self

Specify mods.

Accepted types are

• u32
• rosu_mods::GameModsLegacy
• rosu_mods::GameMods
• rosu_mods::GameModsIntermode
• &rosu_mods::GameModsIntermode

See https://github.com/ppy/osu-api/wiki#mods

pub fn difficulty(self, difficulty: Difficulty) -> Self

Use the specified settings of the given Difficulty.

pub fn passed_objects(self, passed_objects: u32) -> Self

Amount of passed objects for partial plays, e.g. a fail.

If you want to calculate the performance after every few objects, instead of using ManiaPerformance multiple times with different passed_objects, you should use ManiaGradualPerformance.

pub fn clock_rate(self, clock_rate: f64) -> Self

Adjust the clock rate used in the calculation.

If none is specified, it will take the clock rate based on the mods i.e. 1.5 for DT, 0.75 for HT and 1.0 otherwise.

Minimum	Maximum
0.01	100

pub fn hp(self, hp: f32, with_mods: bool) -> Self

Override a beatmap’s set HP.

with_mods determines if the given value should be used before or after accounting for mods, e.g. on true the value will be used as is and on false it will be modified based on the mods.

Minimum	Maximum
-20	20

pub fn od(self, od: f32, with_mods: bool) -> Self

Override a beatmap’s set OD.

with_mods determines if the given value should be used before or after accounting for mods, e.g. on true the value will be used as is and on false it will be modified based on the mods.

Minimum	Maximum
-20	20

pub fn accuracy(self, acc: f64) -> Self

Specify the accuracy of a play between 0.0 and 100.0. This will be used to generate matching hitresults.

pub const fn hitresult_priority(self, priority: HitResultPriority) -> Self

Specify how hitresults should be generated.

Defauls to HitResultPriority::BestCase.

pub fn lazer(self, lazer: bool) -> Self

Whether the calculated attributes belong to an osu!lazer or osu!stable score.

Defaults to true.

This affects internal hitresult generation because lazer (without CL mod) gives two hitresults per hold note whereas stable only gives one. It also affect accuracy calculation because stable makes no difference between perfect (n320) and great (n300) hitresults but lazer (without CL mod) rewards slightly more for perfect hitresults.

pub const fn n320(self, n320: u32) -> Self

Specify the amount of 320s of a play.

pub const fn n300(self, n300: u32) -> Self

Specify the amount of 300s of a play.

pub const fn n200(self, n200: u32) -> Self

Specify the amount of 200s of a play.

pub const fn n100(self, n100: u32) -> Self

Specify the amount of 100s of a play.

pub const fn n50(self, n50: u32) -> Self

Specify the amount of 50s of a play.

pub const fn misses(self, n_misses: u32) -> Self

Specify the amount of misses of a play.

pub const fn state(self, state: ManiaScoreState) -> Self

Provide parameters through an ManiaScoreState.

pub fn generate_state(&mut self) -> Result<ManiaScoreState, ConvertError>

Create the ManiaScoreState that will be used for performance calculation.

pub fn calculate(self) -> Result<ManiaPerformanceAttributes, ConvertError>

Calculate all performance related values, including pp and stars.

Trait Implementations

impl<'map> Clone for ManiaPerformance<'map>

fn clone(&self) -> ManiaPerformance<'map>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'map> Debug for ManiaPerformance<'map>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'map, T: IntoModePerformance<'map, Mania>> From<T> for ManiaPerformance<'map>

fn from(into: T) -> Self

Converts to this type from the input type.

impl<'map> PartialEq for ManiaPerformance<'map>

fn eq(&self, other: &ManiaPerformance<'map>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'map> TryFrom<OsuPerformance<'map>> for ManiaPerformance<'map>

fn try_from(osu: OsuPerformance<'map>) -> Result<Self, Self::Error>

Try to create ManiaPerformance through OsuPerformance.

Returns None if OsuPerformance does not contain a beatmap, i.e. if it was constructed through attributes or OsuPerformance::generate_state was called.

type Error = OsuPerformance<'map>

The type returned in the event of a conversion error.
