Enum Signal 

pub enum Signal {
    Interrupt,
    Terminate,
    Hangup,
    Quit,
}

A process signal an application can subscribe to.

A handler is installed only for a signal the application declared, so a signal it did not declare keeps the process’s default disposition.

SIGWINCH is not here: a size change is the Surface source. Nor does Signal::Interrupt cover Ctrl-C, which under raw mode is an ordinary key on the Input source; it covers the SIGINT another process sends.

Variants

Interrupt

SIGINT, sent from outside the terminal.

Terminate

SIGTERM, the ordinary request to terminate.

Hangup

SIGHUP, the terminal that carried this process went away.

Quit

SIGQUIT.

Trait Implementations

impl Clone for Signal

fn clone(&self) -> Signal

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Signal

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Signal

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Signal

fn eq(&self, other: &Signal) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
