pub struct GameMods { /* private fields */ }
Expand description
Enum for all game modifications. Implemented as bitflags.
Example
use rosu_v2::model::GameMods;
use std::str::FromStr;
let nomod = GameMods::default();
assert_eq!(nomod, GameMods::NoMod);
// Bitwise creating, or from u32
let hdhr_1 = GameMods::HardRock | GameMods::Hidden;
let hdhr_2 = GameMods::from_bits(8 + 16).unwrap();
assert_eq!(hdhr_1, hdhr_2);
// contains, intersects, and a few more methods from bitflags
let ezhdpf = GameMods::Easy | GameMods::Hidden | GameMods::Perfect;
assert!(!ezhdpf.contains(GameMods::HardRock));
let hdpf = GameMods::Hidden | GameMods::Perfect;
assert!(ezhdpf.intersects(hdpf));
// Try converting from &str
let hdhrdt = GameMods::from_str("dthdhr").unwrap();
assert_eq!(hdhrdt.bits(), 8 + 16 + 64);
// Implements fmt::Display
assert_eq!(hdhrdt.to_string(), "HDHRDT".to_string());
// Iterator
let mut mod_iter = GameMods::from_bits(536871512).unwrap().iter();
assert_eq!(mod_iter.next(), Some(GameMods::Hidden));
assert_eq!(mod_iter.next(), Some(GameMods::HardRock));
assert_eq!(mod_iter.next(), Some(GameMods::NightCore));
assert_eq!(mod_iter.next(), Some(GameMods::ScoreV2));
assert_eq!(mod_iter.next(), None);

sourcepub const fn from_bits(bits: u32) -> Option<Self>
pub const fn from_bits(bits: u32) -> Option<Self>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
sourcepub const fn from_bits_truncate(bits: u32) -> Self
pub const fn from_bits_truncate(bits: u32) -> Self
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
sourcepub const unsafe fn from_bits_unchecked(bits: u32) -> Self
pub const unsafe fn from_bits_unchecked(bits: u32) -> Self
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
Safety
The caller of the bitflags!
macro can chose to allow or
disallow extra bits for their bitflags type.
The caller of from_bits_unchecked()
has to ensure that
all bits correspond to a defined flag or that extra bits
are valid for this bitflags type.
sourcepub const fn intersects(&self, other: Self) -> bool
pub const fn intersects(&self, other: Self) -> bool
Returns true
if there are flags common to both self
and other
.
sourcepub const fn contains(&self, other: Self) -> bool
pub const fn contains(&self, other: Self) -> bool
Returns true
if all of the flags in other
are contained within self
.
sourcepub fn set(&mut self, other: Self, value: bool)
pub fn set(&mut self, other: Self, value: bool)
Inserts or removes the specified flags depending on the passed value.
sourcepub const fn intersection(self, other: Self) -> Self
pub const fn intersection(self, other: Self) -> Self
Returns the intersection between the flags in self
and
other
.
Specifically, the returned set contains only the flags which are
present in both self
and other
.
This is equivalent to using the &
operator (e.g.
ops::BitAnd
), as in flags & other
.
sourcepub const fn union(self, other: Self) -> Self
pub const fn union(self, other: Self) -> Self
Returns the union of between the flags in self
and other
.
Specifically, the returned set contains all flags which are
present in either self
or other
, including any which are
present in both (see Self::symmetric_difference
if that
is undesirable).
This is equivalent to using the |
operator (e.g.
ops::BitOr
), as in flags | other
.
sourcepub const fn difference(self, other: Self) -> Self
pub const fn difference(self, other: Self) -> Self
Returns the difference between the flags in self
and other
.
Specifically, the returned set contains all flags present in
self
, except for the ones present in other
.
It is also conceptually equivalent to the “bit-clear” operation:
flags & !other
(and this syntax is also supported).
This is equivalent to using the -
operator (e.g.
ops::Sub
), as in flags - other
.
sourcepub const fn symmetric_difference(self, other: Self) -> Self
pub const fn symmetric_difference(self, other: Self) -> Self
Returns the symmetric difference between the flags
in self
and other
.
Specifically, the returned set contains the flags present which
are present in self
or other
, but that are not present in
both. Equivalently, it contains the flags present in exactly
one of the sets self
and other
.
This is equivalent to using the ^
operator (e.g.
ops::BitXor
), as in flags ^ other
.
sourcepub const fn complement(self) -> Self
pub const fn complement(self) -> Self
Returns the complement of this set of flags.
Specifically, the returned set contains all the flags which are
not set in self
, but which are allowed for this type.
Alternatively, it can be thought of as the set difference
between Self::all()
and self
(e.g. Self::all() - self
)
This is equivalent to using the !
operator (e.g.
ops::Not
), as in !flags
.

sourcepub fn iter(self) -> GameModsIter
pub fn iter(self) -> GameModsIter
Returns an iterator. Alias of into_iter
.
Example
use rosu_v2::model::GameMods;
let mods = GameMods::from_bits(8 + 16 + 64 + 128).unwrap();
let mut mod_iter = mods.iter();
assert_eq!(mod_iter.next(), Some(GameMods::Hidden));

assert_eq!(mod_iter.next(), Some(GameMods::Relax));
assert_eq!(mod_iter.next(), None);
sourcepub fn len(self) -> usize
pub fn len(self) -> usize
Returns the amount of contained mods.
Example
use rosu_v2::model::GameMods;
assert_eq!(GameMods::NoMod.len(), 0);
let mods = GameMods::from_bits(8 + 16 + 64 + 128).unwrap();
assert_eq!(mods.len(), 4);
sourcepub fn clock_rate(self) -> f32
pub fn clock_rate(self) -> f32
Returns the clock rate for the mods i.e. 1.5 for DT, 0.75 for HT, and 1.0 otherwise
