pub struct Signals { /* private fields */ }Available on Linux only.
Expand description
An event source for receiving Unix signals
Implementations
sourceimpl Signals
impl Signals
sourcepub fn new(signals: &[Signal]) -> Result<Signals>
pub fn new(signals: &[Signal]) -> Result<Signals>
Create a new signal event source listening on the specified list of signals
sourcepub fn add_signals(&mut self, signals: &[Signal]) -> Result<()>
pub fn add_signals(&mut self, signals: &[Signal]) -> Result<()>
Add a list of signals to the signals source
If this function returns an error, the signal mask of the thread may have still been changed.
sourcepub fn remove_signals(&mut self, signals: &[Signal]) -> Result<()>
pub fn remove_signals(&mut self, signals: &[Signal]) -> Result<()>
Remove a list of signals from the signals source
If this function returns an error, the signal mask of the thread may have still been changed.
sourcepub fn set_signals(&mut self, signals: &[Signal]) -> Result<()>
pub fn set_signals(&mut self, signals: &[Signal]) -> Result<()>
Replace the list of signals of the source
If this function returns an error, the signal mask of the thread may have still been changed.
