Implementations§
source§impl Ula3CtrlFlags
impl Ula3CtrlFlags
pub const EXT_PAGING: Ula3CtrlFlags = Self{ bits: 1,}
pub const PAGE_LAYOUT_MASK: Ula3CtrlFlags = Self{ bits: 6,}
pub const ROM_BANK_HI: Ula3CtrlFlags = Self{ bits: 4,}
pub const DISC_MOTOR: Ula3CtrlFlags = Self{ bits: 8,}
pub const PRINTER_STROBE: Ula3CtrlFlags = Self{ bits: 16,}
pub const PAGE_LAYOUT0: Ula3CtrlFlags = Self{ bits: 0,}
pub const PAGE_LAYOUT1: Ula3CtrlFlags = Self{ bits: 2,}
pub const PAGE_LAYOUT2: Ula3CtrlFlags = Self{ bits: 4,}
pub const PAGE_LAYOUT3: Ula3CtrlFlags = Self{ bits: 6,}
sourcepub const fn empty() -> Ula3CtrlFlags
pub const fn empty() -> Ula3CtrlFlags
Returns an empty set of flags.
sourcepub const fn all() -> Ula3CtrlFlags
pub const fn all() -> Ula3CtrlFlags
Returns the set containing all flags.
sourcepub const fn from_bits(bits: u8) -> Option<Ula3CtrlFlags>
pub const fn from_bits(bits: u8) -> Option<Ula3CtrlFlags>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
sourcepub const fn from_bits_truncate(bits: u8) -> Ula3CtrlFlags
pub const fn from_bits_truncate(bits: u8) -> Ula3CtrlFlags
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
sourcepub const unsafe fn from_bits_unchecked(bits: u8) -> Ula3CtrlFlags
pub const unsafe fn from_bits_unchecked(bits: u8) -> Ula3CtrlFlags
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: Ula3CtrlFlags) -> bool
pub const fn intersects(&self, other: Ula3CtrlFlags) -> bool
Returns true
if there are flags common to both self
and other
.
sourcepub const fn contains(&self, other: Ula3CtrlFlags) -> bool
pub const fn contains(&self, other: Ula3CtrlFlags) -> bool
Returns true
if all of the flags in other
are contained within self
.
sourcepub fn insert(&mut self, other: Ula3CtrlFlags)
pub fn insert(&mut self, other: Ula3CtrlFlags)
Inserts the specified flags in-place.
sourcepub fn remove(&mut self, other: Ula3CtrlFlags)
pub fn remove(&mut self, other: Ula3CtrlFlags)
Removes the specified flags in-place.
sourcepub fn toggle(&mut self, other: Ula3CtrlFlags)
pub fn toggle(&mut self, other: Ula3CtrlFlags)
Toggles the specified flags in-place.
sourcepub fn set(&mut self, other: Ula3CtrlFlags, value: bool)
pub fn set(&mut self, other: Ula3CtrlFlags, value: bool)
Inserts or removes the specified flags depending on the passed value.
sourcepub const fn intersection(self, other: Ula3CtrlFlags) -> Ula3CtrlFlags
pub const fn intersection(self, other: Ula3CtrlFlags) -> Ula3CtrlFlags
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: Ula3CtrlFlags) -> Ula3CtrlFlags
pub const fn union(self, other: Ula3CtrlFlags) -> Ula3CtrlFlags
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: Ula3CtrlFlags) -> Ula3CtrlFlags
pub const fn difference(self, other: Ula3CtrlFlags) -> Ula3CtrlFlags
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: Ula3CtrlFlags) -> Ula3CtrlFlags
pub const fn symmetric_difference(self, other: Ula3CtrlFlags) -> Ula3CtrlFlags
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) -> Ula3CtrlFlags
pub const fn complement(self) -> Ula3CtrlFlags
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
.
source§impl Ula3CtrlFlags
impl Ula3CtrlFlags
sourcepub fn with_special_paging(self, paging: Ula3Paging) -> Ula3CtrlFlags
pub fn with_special_paging(self, paging: Ula3Paging) -> Ula3CtrlFlags
Returns modified flags with the special paging enabled and its layout set to the specified value.
sourcepub fn with_rom_page_bank_hi(self, rom_bank: usize) -> Ula3CtrlFlags
pub fn with_rom_page_bank_hi(self, rom_bank: usize) -> Ula3CtrlFlags
Returns modified flags with the special paging disabled and with the rom bank high flag set from
the rom_bank
bit1.
sourcepub fn has_special_paging(self) -> bool
pub fn has_special_paging(self) -> bool
Returns true
if a special paging is enabled. Otherwise returns false
.
sourcepub fn special_paging(self) -> Option<Ula3Paging>
pub fn special_paging(self) -> Option<Ula3Paging>
Returns a special paging layout if it is enabled.
sourcepub fn rom_page_bank_hi(self) -> usize
pub fn rom_page_bank_hi(self) -> usize
Returns a bit 1 value of rom bank index mapped at the first RAM page.
The complete rom page bank index can be obtained by bitwise ORing the returned value with the result from Ula128MemFlags::rom_page_bank.
sourcepub fn is_disc_motor_on(self) -> bool
pub fn is_disc_motor_on(self) -> bool
Returns true
if a disc motor bit is 1. Otherwise returns false
.
sourcepub fn is_printer_strobe_on(self) -> bool
pub fn is_printer_strobe_on(self) -> bool
Returns true
if a printer strobe bit is 1. Otherwise returns false
.
