Struct syscall::flag::EventFlags

pub struct EventFlags { /* fields omitted */ }

Implementations

impl EventFlags

pub const EVENT_NONE: EventFlags

pub const EVENT_READ: EventFlags

The event represents a file being able to be read from.

pub const EVENT_WRITE: EventFlags

The event represents a file being able to be written to.

pub const EVENT_URING: EventFlags

The event represents an io_uring getting a new submission or completion pushed onto it, which means that a process receiving this event can poll that queue and process its events.

This event may be sent as all other Redox events by writing to the fd, but to reduce context switches as much as possible, the kernel may also compare the epoch counters of a process's io_urings and generate the event automatically.

pub const fn empty() -> EventFlags

Returns an empty set of flags

pub const fn all() -> EventFlags

Returns the set containing all flags.

pub const fn bits(&self) -> usize

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: usize) -> Option<EventFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: usize) -> EventFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: usize) -> EventFlags

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: EventFlags) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: EventFlags) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: EventFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: EventFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: EventFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: EventFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.
