Struct crankit_input::ButtonSet

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

Set of Button

Implementations

impl Set

pub const D_PAD: Self = _

The set of 4 D-Pad buttons (up, down, left, right)

pub fn new() -> Self

pub fn insert(&mut self, button: Button)

pub fn contains(self, button: Button) -> bool

Returns true if the set contains the button

pub fn contains_any(self, buttons: impl Into<Self>) -> bool

Returns true if the set contains any of the buttons in the other set.

Returns false if the other set is empty.

pub fn d_pad<T: From<i8>>(self) -> [T; 2]

Returns the d-pad buttons contained in this set as a 2d vector

The axes correspond to the playdate screen coordinate system (x is right, and y is down):

• Left is [-1, 0]
• Right is [1, 0]
• Down is [0, 1]
• Up is [0, -1]

If more than one D-Pad button is contained in the set, this method returns the sum of the vectors.

Trait Implementations

impl Clone for Set

fn clone(&self) -> Set

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Set

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

Formats the value using the given formatter.

impl Default for Set

fn default() -> Set

Returns the “default value” for a type.

impl Extend<Button> for Set

fn extend<T: IntoIterator<Item = Button>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl From<&[Button]> for Set

fn from(value: &[Button]) -> Self

Converts to this type from the input type.

impl<const N: usize> From<[Button; N]> for Set

fn from(value: [Button; N]) -> Self

Converts to this type from the input type.

impl From<Button> for Set

fn from(value: Button) -> Self

Converts to this type from the input type.

impl FromIterator<Button> for Set

fn from_iter<T: IntoIterator<Item = Button>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq for Set

fn eq(&self, other: &Set) -> 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.
