Enum SystemControlKey 

#[non_exhaustive]
#[repr(u16)]
pub enum SystemControlKey {

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.

No = 0

PowerDown = 129

Sleep = 130

WakeUp = 131

Restart = 143

Implementations

impl SystemControlKey

pub const fn from_repr(discriminant: u16) -> Option<SystemControlKey>

Try to create Self from the raw representation

Trait Implementations

impl Clone for SystemControlKey

fn clone(&self) -> SystemControlKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SystemControlKey

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

Formats the value using the given formatter.

impl From<u16> for SystemControlKey

fn from(value: u16) -> Self

Converts to this type from the input type.

impl Ord for SystemControlKey

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

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

fn partial_cmp(&self, other: &SystemControlKey) -> 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.
