Trait Implementations

impl Clone for Leds

fn clone(&self) -> Leds

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Leds

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

Formats the value using the given formatter.

impl Default for Leds

fn default() -> Self

Returns the “default value” for a type.

impl From<Leds> for u8

fn from(enum_value: Leds) -> Self

Converts to this type from the input type.

impl From<u8> for Leds

fn from(number: u8) -> Self

Converts to this type from the input type.

impl FromPrimitive for Leds

type Primitive = u8

fn from_primitive(number: Self::Primitive) -> Self

impl Hash for Leds

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 Leds

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

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

fn partial_cmp(&self, other: &Leds) -> 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 PrimitiveEnum for Leds

type Primitive = u8

The primitve type into which we serialize and deserialize ourselves.

fn from_primitive(val: u8) -> Option<Self>

Convert from a primitive, might fail.

fn to_primitive(&self) -> u8

Convert to a primitive value.

fn from_str(s: &str) -> Option<Self>

Convert from a string value representing the variant. Case sensitive.

fn from_str_lower(s: &str) -> Option<Self>

Convert from a string value representing the variant. Lowercase.

impl PrimitiveEnumStaticStr for Leds

fn to_display_str(&self) -> &'static str

Display value, same as the name of a particular variant.

fn all_variants() -> &'static [Self]

A list all possible string variants.

impl Copy for Leds

impl Eq for Leds

impl StructuralPartialEq for Leds
