impl SigSet

fn all() -> SigSet

Initialize to include all signals.

fn empty() -> SigSet

Initialize to include nothing.

fn add(&mut self, signal: Signal)

Add the specified signal to the set.

fn clear(&mut self)

Remove all signals from this set.

fn remove(&mut self, signal: Signal)

Remove the specified signal from this set.

fn contains(&self, signal: Signal) -> bool

Return whether this set includes the specified signal.

fn iter(&self) -> SigSetIter<'_>

Returns an iterator that yields the signals contained in this set.

fn thread_get_mask() -> Result<SigSet>

Gets the currently blocked (masked) set of signals for the calling thread.

fn thread_set_mask(&self) -> Result<()>

Sets the set of signals as the signal mask for the calling thread.

fn thread_block(&self) -> Result<()>

Adds the set of signals to the signal mask for the calling thread.

fn thread_unblock(&self) -> Result<()>

Removes the set of signals from the signal mask for the calling thread.

fn thread_swap_mask(&self, how: SigmaskHow) -> Result<SigSet>

Sets the set of signals as the signal mask, and returns the old mask.

fn wait(&self) -> Result<Signal>

Suspends execution of the calling thread until one of the signals in the signal mask becomes pending, and returns the accepted signal.

fn suspend(&self) -> Result<()>

Wait for a signal

Return value

If sigsuspend(2) is interrupted (EINTR), this function returns Ok. If sigsuspend(2) set other error, this function returns Err.

For more information see the sigsuspend(2).

unsafe fn from_sigset_t_unchecked(sigset: sigset_t) -> SigSet

Converts a libc::sigset_t object to a SigSet without checking whether the libc::sigset_t is already initialized.

Safety

The sigset passed in must be a valid an initialized libc::sigset_t by calling either sigemptyset(3) or sigfillset(3). Otherwise, the results are undefined.
