Implementations

impl KeyCode

pub fn is_modifier(self) -> bool

Returns true if the key code correspond to a modifier (send separately on USB HID report).

pub fn as_modifier_bit(self) -> u8

Returns the byte with the bit corresponding to the USB HID modifier bitfield setted.

Trait Implementations

impl Clone for KeyCode

fn clone(&self) -> KeyCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyCode

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

Formats the value using the given formatter.

impl FromIterator<KeyCode> for KbHidReport

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

where T: IntoIterator<Item = KeyCode>,

Creates a value from an iterator.

impl Ord for KeyCode

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

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

fn partial_cmp(&self, other: &KeyCode) -> 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 Copy for KeyCode

impl Eq for KeyCode

impl StructuralPartialEq for KeyCode
