Implementations
impl SetupFlags
[src]
pub const IOPOLL: SetupFlags
[src]
Poll the IO context instead of defaulting to interrupts.
pub const SQPOLL: SetupFlags
[src]
Assign a kernel thread to poll the submission queue. Requires elevated privileges to set.
pub const SQ_AFF: SetupFlags
[src]
Force the kernel thread created with SQPOLL
to be bound to the CPU used by the
SubmissionQueue
. Requires SQPOLL
set.
pub const CQSIZE: SetupFlags
[src]
pub const CLAMP: SetupFlags
[src]
pub const ATTACH_WQ: SetupFlags
[src]
pub const fn empty() -> SetupFlags
[src]
Returns an empty set of flags
pub const fn all() -> SetupFlags
[src]
Returns the set containing all flags.
pub const fn bits(&self) -> u32
[src]
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: u32) -> Option<SetupFlags>
[src]
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: u32) -> SetupFlags
[src]
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: u32) -> SetupFlags
[src]
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
pub const fn is_empty(&self) -> bool
[src]
Returns true
if no flags are currently stored.
pub const fn is_all(&self) -> bool
[src]
Returns true
if all flags are currently set.
pub const fn intersects(&self, other: SetupFlags) -> bool
[src]
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: SetupFlags) -> bool
[src]
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: SetupFlags)
[src]
Inserts the specified flags in-place.
pub fn remove(&mut self, other: SetupFlags)
[src]
Removes the specified flags in-place.
pub fn toggle(&mut self, other: SetupFlags)
[src]
Toggles the specified flags in-place.
pub fn set(&mut self, other: SetupFlags, value: bool)
[src]
Inserts or removes the specified flags depending on the passed value.
