Struct libnoentiendo::keyboard::KeyState

pub struct KeyState<T: PartialEq + Clone> { /* private fields */ }

A set of keys that are currently pressed. Parameter T is the type of the key symbols.

Implementations

impl<T: PartialEq + Clone> KeyState<T>

pub fn new() -> Self

Creates a new, empty key state.

pub fn press(&mut self, symbol: T)

Adds a key to the set of pressed keys.

pub fn release(&mut self, symbol: T)

Removes a key from the set of pressed keys.

pub fn pressed(&self) -> impl Iterator<Item = &T>

Return the set of pressed keys.

pub fn is_pressed(&self, symbol: T) -> bool

Returns true if the given key is currently pressed.

pub fn is_empty(&self) -> bool

Returns true if the set of keys is empty.

pub fn get_one_key(&self) -> Option<T>

Returns the most recent key pressed.

Trait Implementations

impl<T: PartialEq + Clone> BitOr for KeyState<T>

type Output = KeyState<T>

The resulting type after applying the | operator.

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

Performs the | operation.

impl<T: Clone + PartialEq + Clone> Clone for KeyState<T>

fn clone(&self) -> KeyState<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + PartialEq + Clone> Debug for KeyState<T>

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

Formats the value using the given formatter.

impl<T: Default + PartialEq + Clone> Default for KeyState<T>

fn default() -> KeyState<T>

Returns the “default value” for a type.

impl<T: PartialEq + PartialEq + Clone> PartialEq for KeyState<T>

fn eq(&self, other: &KeyState<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
