Struct SigintForwarder 

pub struct SigintForwarder { /* private fields */ }

RAII guard installing the SIGINT-forwarding handler for the duration of one ask subprocess, restoring the previous disposition (and clearing the pgid) on drop. The fno ask client is one-shot, so only one ask child is ever in flight per process.

Implementations

impl SigintForwarder

pub fn install(pgid: u32) -> Self

Install the handler, pointing it at pgid (== child pid, since the child is setpgid(0, 0) into its own group).

Trait Implementations

impl Drop for SigintForwarder

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
