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

Available on crate feature signal only.

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<Signal> for SigSet

Available on crate feature signal only.

type Output = SigSet

The resulting type after applying the | operator.

fn bitor(self, rhs: Signal) -> Self::Output

Performs the | operation.

impl BitOr for Signal

Available on crate feature signal only.

type Output = SigSet

The resulting type after applying the | operator.

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

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 Display for Signal

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

Formats the value using the given formatter.

impl Extend<Signal> for SigSet

Available on crate feature signal only.

fn extend<T>(&mut self, iter: T)

where T: IntoIterator<Item = Signal>,

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

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

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

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

Reserves capacity in a collection for the given number of additional elements.

impl From<Signal> for SigSet

Available on crate feature signal only.

fn from(signal: Signal) -> SigSet

Converts to this type from the input type.

impl FromIterator<Signal> for SigSet

Available on crate feature signal only.

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = Signal>,

Creates a value from an iterator.

impl FromStr for Signal

type Err = Errno

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this 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.

impl TryFrom<i32> for Signal

type Error = Errno

The type returned in the event of a conversion error.

fn try_from(x: i32) -> Result<Self>

Performs the conversion.

impl Copy for Signal

impl Eq for Signal

impl StructuralPartialEq for Signal

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
