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.

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 BitOr for Signal

type Output = SigSet

The resulting type after applying the | operator.

fn bitor(self, rhs: Signal) -> <Signal as BitOr>::Output

Performs the | operation.

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) -> 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.

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 StructuralPartialEq for Signal
