Struct NoOpKeyState

pub struct NoOpKeyState<Ctx, Ev>(/* private fields */);

A NoOp key state, for keys which do nothing when pressed.

Implementations

impl<Ctx, Ev> NoOpKeyState<Ctx, Ev>

pub const fn new() -> Self

Constructs a NoOpKeyState value.

Trait Implementations

impl<Ctx: Clone, Ev: Clone> Clone for NoOpKeyState<Ctx, Ev>

fn clone(&self) -> NoOpKeyState<Ctx, Ev>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Ctx: Debug, Ev: Debug> Debug for NoOpKeyState<Ctx, Ev>

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

Formats the value using the given formatter.

impl From<NoOpKeyState<Context, Event>> for KeyState

fn from(_: NoOpKeyState<Context, Event>) -> Self

Converts to this type from the input type.

impl<Ctx: Debug, Ev: Copy + Debug> KeyState for NoOpKeyState<Ctx, Ev>

type Context = Ctx

The type of Context the pressed key state handles.

type Event = Ev

The type of Event the pressed key state handles.

fn handle_event( &mut self, _context: &Self::Context, _keymap_index: u16, _event: Event<Self::Event>, ) -> KeyEvents<Self::Event>

Used to update the KeyState’s state, and possibly yield event(s).

fn key_output(&self) -> Option<KeyOutput>

Output for the pressed key state.

impl<Ctx: PartialEq, Ev: PartialEq> PartialEq for NoOpKeyState<Ctx, Ev>

fn eq(&self, other: &NoOpKeyState<Ctx, Ev>) -> 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.
