Enum Signal 

pub enum Signal {
    Interrupt,
    Terminate,
    Quit,
    User1,
    User2,
}

Process signal returned by Signals.

Variants

Interrupt

Interrupt signal.

This signal is received by the process when its controlling terminal wishes to interrupt the process. This signal will for example be send when Ctrl+C is pressed in most terminals.

Corresponds to POSIX signal SIGINT.

Terminate

Termination request signal.

This signal received when the process is requested to terminate. This allows the process to perform nice termination, releasing resources and saving state if appropriate. This signal will be send when using the kill command for example.

Corresponds to POSIX signal SIGTERM.

Quit

Terminal quit signal.

This signal is received when the process is requested to quit and perform a core dump.

Corresponds to POSIX signal SIGQUIT.

User1

User-defined signal 1.

Corresponds to POSIX signal SIGUSR1.

User2

User-defined signal 2.

Corresponds to POSIX signal SIGUSR2.

Trait Implementations

Performs the | operation.

impl BitOr<SignalSet> for Signal

type Output = SignalSet

The resulting type after applying the | operator.

fn bitor(self, rhs: SignalSet) -> SignalSet

Performs the | operation.

impl BitOr for Signal

type Output = SignalSet

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> SignalSet

Performs the | operation.

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 From<Signal> for SignalSet

fn from(signal: Signal) -> Self

Converts to this type from the input type.

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 Ord for Signal

fn cmp(&self, other: &Signal) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for Signal

fn partial_cmp(&self, other: &Signal) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
