Struct ButtonState 

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

Result of one pad poll. bits() gives the raw active-high mask; ButtonState::is_held is the ergonomic per-button check.

Implementations

impl ButtonState

pub const NONE: Self

Empty – nothing held.

pub const fn from_bits(bits: u16) -> Self

Construct from an active-high mask.

pub const fn bits(self) -> u16

Raw bitmask.

pub const fn pressed_since(self, previous: Self, mask: u16) -> bool

True when any masked button is down now and none was down previously. For multi-button masks this is a group edge, not a per-button edge.

pub const fn is_held(self, mask: u16) -> bool

true when mask (any single-bit button constant or an OR of several) is currently pressed.

Trait Implementations

impl Clone for ButtonState

fn clone(&self) -> ButtonState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ButtonState

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

Formats the value using the given formatter.

impl Default for ButtonState

fn default() -> ButtonState

Returns the “default value” for a type.

impl PartialEq for ButtonState

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