Struct CatchPerformance 

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

Performance calculator on osu!catch maps.

Implementations

impl<'map> CatchPerformance<'map>

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

Create a new performance calculator for osu!catch maps.

The argument map_or_attrs must be either

• previously calculated attributes (CatchDifficultyAttributes or CatchPerformanceAttributes)
• 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!catch maps.

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

See CatchPerformance::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 const fn combo(self, combo: u32) -> Self

Specify the max combo of the play.

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

Specify the amount of fruits of a play i.e. n300.

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

Specify the amount of droplets of a play i.e. n100.

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

Specify the amount of tiny droplets of a play i.e. n50.

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

Specify the amount of tiny droplet misses of a play i.e. n_katu.

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

Specify the amount of fruit / droplet misses of the play.

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 CatchPerformance multiple times with different passed_objects, you should use CatchGradualPerformance.

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 ar(self, ar: f32, with_mods: bool) -> Self

Override a beatmap’s set AR.

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 cs(self, cs: f32, with_mods: bool) -> Self

Override a beatmap’s set CS.

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 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 hardrock_offsets(self, hardrock_offsets: bool) -> Self

Adjust patterns as if the HR mod is enabled.

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

Provide parameters through an CatchScoreState.

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

Create the CatchScoreState that will be used for performance calculation.

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

Calculate all performance related values, including pp and stars.

Trait Implementations

impl<'map> Clone for CatchPerformance<'map>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'map> Debug for CatchPerformance<'map>

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

Formats the value using the given formatter.

impl<'map, T: IntoModePerformance<'map, Catch>> From<T> for CatchPerformance<'map>

fn from(into: T) -> Self

Converts to this type from the input type.

impl<'map> PartialEq for CatchPerformance<'map>

fn eq(&self, other: &CatchPerformance<'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 CatchPerformance<'map>

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

Try to create CatchPerformance 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.
