Implementations§
§impl Command
impl Command
pub const MEMORY_SPACE: Command = Self{ bits: 1 << 1,}
pub const MEMORY_SPACE: Command = Self{ bits: 1 << 1,}
The device can respond to Memory Space accesses.
pub const BUS_MASTER: Command = Self{ bits: 1 << 2,}
pub const BUS_MASTER: Command = Self{ bits: 1 << 2,}
The device can behave as a bus master.
pub const SPECIAL_CYCLES: Command = Self{ bits: 1 << 3,}
pub const SPECIAL_CYCLES: Command = Self{ bits: 1 << 3,}
The device can monitor Special Cycle operations.
pub const MEMORY_WRITE_AND_INVALIDATE_ENABLE: Command = Self{ bits: 1 << 4,}
pub const MEMORY_WRITE_AND_INVALIDATE_ENABLE: Command = Self{ bits: 1 << 4,}
The device can generate the Memory Write and Invalidate command.
pub const VGA_PALETTE_SNOOP: Command = Self{ bits: 1 << 5,}
pub const VGA_PALETTE_SNOOP: Command = Self{ bits: 1 << 5,}
The device will snoop palette register data.
pub const PARITY_ERROR_RESPONSE: Command = Self{ bits: 1 << 6,}
pub const PARITY_ERROR_RESPONSE: Command = Self{ bits: 1 << 6,}
The device should take its normal action when a parity error is detected.
pub const SERR_ENABLE: Command = Self{ bits: 1 << 8,}
pub const SERR_ENABLE: Command = Self{ bits: 1 << 8,}
The SERR# driver is enabled.
pub const FAST_BACK_TO_BACK_ENABLE: Command = Self{ bits: 1 << 9,}
pub const FAST_BACK_TO_BACK_ENABLE: Command = Self{ bits: 1 << 9,}
The device is allowed to generate fast back-to-back transactions.
pub const INTERRUPT_DISABLE: Command = Self{ bits: 1 << 10,}
pub const INTERRUPT_DISABLE: Command = Self{ bits: 1 << 10,}
Assertion of the device’s INTx# signal is disabled.
pub const fn from_bits(bits: u16) -> Option<Command>
pub const fn from_bits(bits: u16) -> Option<Command>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: u16) -> Command
pub const fn from_bits_truncate(bits: u16) -> Command
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: u16) -> Command
pub const unsafe fn from_bits_unchecked(bits: u16) -> Command
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.
pub const fn intersects(&self, other: Command) -> bool
pub const fn intersects(&self, other: Command) -> bool
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: Command) -> bool
pub const fn contains(&self, other: Command) -> bool
Returns true
if all of the flags in other
are contained within self
.
pub fn set(&mut self, other: Command, value: bool)
pub fn set(&mut self, other: Command, value: bool)
Inserts or removes the specified flags depending on the passed value.
pub const fn intersection(self, other: Command) -> Command
pub const fn intersection(self, other: Command) -> Command
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
.
pub const fn union(self, other: Command) -> Command
pub const fn union(self, other: Command) -> Command
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
.
pub const fn difference(self, other: Command) -> Command
pub const fn difference(self, other: Command) -> Command
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
.
pub const fn symmetric_difference(self, other: Command) -> Command
pub const fn symmetric_difference(self, other: Command) -> Command
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
.
pub const fn complement(self) -> Command
pub const fn complement(self) -> Command
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
.
