Enum Key

pub enum Key<C = SmolStr> {
    Named(Named),
    Character(C),
    Unidentified,
}

A key on the keyboard.

This is mostly the Key type found in winit.

Variants

Named(Named)

A key with an established name.

Character(C)

A key string that corresponds to the character typed by the user, taking into account the user’s current locale setting, and any system-level keyboard mapping overrides that are in effect.

Unidentified

An unidentified key.

Implementations

impl Key

pub fn as_ref(&self) -> Key<&str>

Convert Key::Character(SmolStr) to Key::Character(&str) so you can more easily match on Key. All other variants remain unchanged.

Trait Implementations

impl<C: Clone> Clone for Key<C>

fn clone(&self) -> Key<C>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<C: Debug> Debug for Key<C>

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

Formats the value using the given formatter.

impl From<Named> for Key

fn from(named: Named) -> Self

Converts to this type from the input type.

impl<C: Hash> Hash for Key<C>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<C: Ord> Ord for Key<C>

fn cmp(&self, other: &Key<C>) -> 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<C: PartialEq> PartialEq for Key<C>

fn eq(&self, other: &Key<C>) -> 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<C: PartialOrd> PartialOrd for Key<C>

fn partial_cmp(&self, other: &Key<C>) -> 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.
