Types of operating system signals

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SIGHUP

Hangup

SIGINT

Interrupt

SIGQUIT

Quit

SIGILL

Illegal instruction (not reset when caught)

SIGTRAP

Trace trap (not reset when caught)

SIGABRT

Abort

SIGBUS

Bus error

SIGFPE

Floating point exception

SIGKILL

Kill (cannot be caught or ignored)

SIGUSR1

User defined signal 1

SIGSEGV

Segmentation violation

SIGUSR2

User defined signal 2

SIGPIPE

Write on a pipe with no one to read it

SIGALRM

Alarm clock

SIGTERM

Software termination signal from kill

SIGSTKFLT

Stack fault (obsolete)

SIGCHLD

To parent on child stop or exit

SIGCONT

Continue a stopped process

SIGSTOP

Sendable stop signal not from tty

SIGTSTP

Stop signal from tty

SIGTTIN

To readers pgrp upon background tty read

SIGTTOU

Like TTIN if (tp->t_local&LTOSTOP)

SIGURG

Urgent condition on IO channel

SIGXCPU

Exceeded CPU time limit

SIGXFSZ

Exceeded file size limit

SIGVTALRM

Virtual time alarm

SIGPROF

Profiling time alarm

SIGWINCH

Window size changes

SIGIO

Input/output possible signal

SIGPWR

Power failure imminent.

SIGSYS

Bad system call

Implementations

impl Signal

pub const fn as_str(self) -> &'static str

Returns name of signal.

This function is equivalent to <Signal as AsRef<str>>::as_ref(), with difference that returned string is 'static and not bound to self’s lifetime.

impl Signal

pub const fn iterator() -> SignalIterator

Iterate through all signals defined by this OS

Trait Implementations

impl AsRef<str> for Signal

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Signal

fn clone(&self) -> Signal

Returns a copy 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<(), Error>

Formats the value using the given formatter.

impl Display for Signal

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

Formats the value using the given formatter.

impl FromStr for Signal

type Err = Errno

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Signal, Errno>

Parses a string s to return a value of this type.

impl Hash for Signal

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

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) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Signal> for Signal

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<Signal> 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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl TryFrom<i32> for Signal

type Error = Errno

The type returned in the event of a conversion error.

fn try_from(x: i32) -> Result<Signal, Errno>

Performs the conversion.

impl Copy for Signal

impl Eq for Signal

impl StructuralEq for Signal

impl StructuralPartialEq for Signal
