Struct SignalFd

pub struct SignalFd(/* private fields */);

Special file descriptor from which Signals directed to the caller can be read

Note that a signal fd must not derive neither Clone nor Copy!

Implementations

impl SignalFd

pub fn new(signals: SignalSet) -> Result<SignalFd>

Return a SignalFd that will be able to read the signals given in the signal set signals.

pub fn read_signal(&mut self) -> Result<Signal>

Read and return a Signal

Note this function will block until a signal could be read.

Trait Implementations

impl Debug for SignalFd

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

Formats the value using the given formatter.

impl Drop for SignalFd

fn drop(&mut self)

Drop the SignalFd

Dropping a signal fd involves calling libc::close(). Note that close is special in the sense that all errors except an invalid signal fd should simply be ignored.

impl PartialEq for SignalFd

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Source for SignalFd

fn register( &mut self, registry: &Registry, token: Token, interests: Interest, ) -> Result<()>

Register self with the given Registry instance.

fn reregister( &mut self, registry: &Registry, token: Token, interests: Interest, ) -> Result<()>

Re-register self with the given Registry instance.

fn deregister(&mut self, registry: &Registry) -> Result<()>

Deregister self from the given Registry instance.
