Struct Source 

pub struct Source<'process> { /* private fields */ }

Linear process-lifetime view of the termination signal receiver.

Implementations

impl Source<'_>

pub fn scope<'owner, R, E>( retained: Vacant<'owner, Receiver>, run: impl for<'process> FnOnce(Source<'process>) -> Result<R, E>, ) -> Result<R, Error<'owner, E>>

Enters the exclusive signal scope on the process’s original thread. Call during single-threaded startup. Other code must not change SIGTERM handling while run executes; masks on other existing threads are not updated. Workers must start inside run and finish before the policy is restored.

Trait Implementations

impl AsFd for Source<'_>

fn as_fd(&self) -> BorrowedFd<'_>

Borrows the file descriptor.

impl Signal for Source<'_>

type Error = <<Uring as Thread>::Receiver as Receiver>::Wait

fn wait(&self) -> Result<(), Self::Error>

Consumes a pending signal after descriptor readiness. The caller retains sole consumption authority between observing readiness and this call.
