[−][src]Struct scoped_signal::SignalScope

pub struct SignalScope<F> { /* fields omitted */ }

Install a signal handler only valid for a given scope

Methods

impl<Handler: Fn(u8, &SigInfo)> SignalScope<Handler>[src]

pub unsafe fn new(
    signal: Signal,
    flags: SaFlags,
    set: SigSet,
    handler: Handler
) -> Self[src]

Create an object representing the provided signal handler. The handler is only called in the thread that run() is called from. If another thread receives the same signal, the signal will be ignored unless the thread is using its own SignalScope for the same signal

set defines what signals are blocked during the execution of the signal handler itself

See sigaction(3P) for more info

Safety

This is an unsafe operation because the passed handler must only call async-signal-safe functions and we cannot verify this

pub fn run<T, F: FnOnce() -> T>(self, f: F) -> Result<T, Error>[src]

Run the given closure with this signal handler installed
