Struct Number 

pub struct Number(/* private fields */);

Signal number

This is a wrapper type for signal numbers. It is guaranteed to be a positive integer, so it optimizes the size of Option<Number>, etc.

To make sure that all Numbers are valid, you can only obtain a Number from an instance of System. Use the System::validate_signal and System::signal_number_from_name methods to create a Number from a raw signal number or a signal name, respectively.

Signal numbers are specific to the underlying system. Passing a signal number obtained from RealSystem to VirtualSystem (or vice versa) is not supported and may result in unexpected behavior, though it is not checked by the type system.

Implementations

impl Number

pub const fn as_raw(self) -> RawNumber

Returns the raw signal number.

pub const fn as_raw_non_zero(self) -> NonZero<RawNumber>

Returns the raw signal number as a NonZero<RawNumber>.

pub const fn from_raw_unchecked(raw: NonZero<RawNumber>) -> Self

Creates a new Number from a raw signal number.

This is a backdoor method that allows creating a Number from an arbitrary raw signal number. The caller must ensure that the raw signal number is a valid signal number.

This function is not marked unsafe because creating an invalid Number does not lead to undefined behavior. However, it is not recommended to use this function unless you are sure that the raw signal number is valid. To make sure that all Numbers are valid, use the System::validate_signal and System::signal_number_from_name methods instead.

Trait Implementations

impl Binary for Number

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

Formats the value using the given formatter.

impl Clone for Number

fn clone(&self) -> Number

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Number

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

Formats the value using the given formatter.

impl Display for Number

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

Formats the value using the given formatter.

impl From<Number> for Condition

fn from(number: Number) -> Self

Converts to this type from the input type.

impl From<Number> for ExitStatus

Converts a signal number to the corresponding exit status.

POSIX requires the exit status to be greater than 128. The current implementation returns signal_number + 384.

See ExitStatus::to_signal for the reverse conversion.

fn from(number: Number) -> Self

Converts to this type from the input type.

impl Hash for Number

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 LowerHex for Number

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

Formats the value using the given formatter.

impl Octal for Number

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

Formats the value using the given formatter.

impl Ord for Number

fn cmp(&self, other: &Number) -> 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 Number

fn eq(&self, other: &Number) -> 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 Number

fn partial_cmp(&self, other: &Number) -> 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 UpperHex for Number

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

Formats the value using the given formatter.

impl Copy for Number

impl Eq for Number

impl StructuralPartialEq for Number
