Struct nix::sys::signal::SigEvent

#[repr(C)]
pub struct SigEvent { /* private fields */ }

Used to request asynchronous notification of the completion of certain events, such as POSIX AIO and timers.

Implementations

impl SigEvent

pub fn new(sigev_notify: SigevNotify) -> SigEvent

Note: this constructor does not allow the user to set the sigev_notify_kevent_flags field. That’s considered ok because on FreeBSD at least those flags don’t do anything useful. That field is part of a union that shares space with the more genuinely useful fields.

Note: This constructor also doesn’t allow the caller to set the sigev_notify_function or sigev_notify_attributes fields, which are required for SIGEV_THREAD. That’s considered ok because on no operating system is SIGEV_THREAD the most efficient way to deliver AIO notification. FreeBSD and DragonFly BSD programs should prefer SIGEV_KEVENT. Linux, Solaris, and portable programs should prefer SIGEV_THREAD_ID or SIGEV_SIGNAL. That field is part of a union that shares space with the more genuinely useful sigev_notify_thread_id

pub fn sigevent(&self) -> sigevent

Return a copy of the inner structure

pub fn as_mut_ptr(&mut self) -> *mut sigevent

Returns a mutable pointer to the sigevent wrapped by self

Trait Implementations

impl Clone for SigEvent

fn clone(&self) -> SigEvent

Returns a copy of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SigEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> From<&'a sigevent> for SigEvent

fn from(sigevent: &sigevent) -> Self

Converts to this type from the input type.

impl Hash for SigEvent

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl PartialEq<SigEvent> for SigEvent

fn eq(&self, other: &SigEvent) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
