[−][src]Struct linux_aio_tokio::ReadFlags
AIO read flags. See io_submit
Methods
impl ReadFlags
[src]
pub const HIPRI: ReadFlags
[src]
High priority request, poll if possible
pub const NOWAIT: ReadFlags
[src]
Don't wait if the I/O will block for operations such as
file block allocations, dirty page flush, mutex locks,
or a congested block device inside the kernel. If any
of these conditions are met, the control block is
returned immediately with a return value of -EAGAIN
in
the res field of the io_event structure.
pub const fn empty() -> ReadFlags
[src]
Returns an empty set of flags
pub const fn all() -> ReadFlags
[src]
Returns the set containing all flags.
pub const fn bits(&self) -> isize
[src]
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: isize) -> Option<ReadFlags>
[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: isize) -> ReadFlags
[src]
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: isize) -> ReadFlags
[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: ReadFlags) -> bool
[src]
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: ReadFlags) -> bool
[src]
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: ReadFlags)
[src]
Inserts the specified flags in-place.
pub fn remove(&mut self, other: ReadFlags)
[src]
Removes the specified flags in-place.
pub fn toggle(&mut self, other: ReadFlags)
[src]
Toggles the specified flags in-place.
pub fn set(&mut self, other: ReadFlags, value: bool)
[src]
Inserts or removes the specified flags depending on the passed value.
