Struct SigSet 

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

A wrapper for libc::sigset_t

Implementations

impl SigSet

pub fn new() -> Self

Create new, empty SigSet

pub fn clear(&mut self) -> &mut Self

Clear all signals in SigSet

pub fn fill(&mut self) -> &mut Self

Set all signals in SigSet

pub fn add(&mut self, sig: Sig) -> &mut Self

Add a signle Sig to SigSet.

Re-adding already existing signal does nothing.

pub fn add_many(&mut self, sigs: &[Sig]) -> &mut Self

Add a list of Sigs to SigSet.

Re-adding already existing signals does nothing.

pub fn remove(&mut self, sig: Sig) -> &mut Self

Remove a signle Sig from SigSet.

Removing already removed signal does nothing.

pub fn remove_many(&mut self, sigs: &[Sig]) -> &mut Self

Remove a list of Sigs from SigSet.

Removing already removed signals does nothing.

pub fn has(&self, sig: Sig) -> bool

Check if Signal is present in SigSet

pub fn has_any(&self, sigs: &[Sig]) -> bool

Check if SigSet has any of Signals from the list set

pub fn has_all(&self, sigs: &[Sig]) -> bool

Check if SigSet has all of Signals from the list set

pub fn disable_default_handler(&self) -> Result<()>

Detach SigSet from default handlers.

Specified signals are ignored by runtime but can be handled by user-defined handlers, for example by [mio-signalfd].

pub fn enable_default_handler(&self) -> Result<()>

Attach a SigSet to default handlers.

Specified signals are handled by runtime according to default rules, which may prevent signal from reaching user-defined handler.

pub fn from(sigs: &[Sig]) -> Self

Create SigSet pre-populated with list of Sigs

pub fn as_ptr(&self) -> *const sigset_t

Expose as const pointer to underlying libc::sigset_t

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

Expose as mut pointer to underlying libc::sigset_t
