Enum Key 

pub enum Key {
    Character(String),
    Named(NamedKey),
}

Standardized keyboard values shared by every platform adapter.

Code identifies the physical key position; Key is the logical key value after the operating system’s layout processing. Incular does not maintain a parallel keyboard vocabulary. The value received from the keypress.

Variants

Character(String)

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

Named(NamedKey)

Implementations

impl Key

pub fn legacy_charcode(&self) -> u32

Determine a charCode value for a key with a character value.

For all other keys the value is zero. The charCode is an implementation specific legacy property of DOM keyboard events.

Specification: https://w3c.github.io/uievents/#dom-keyboardevent-charcode

pub fn legacy_keycode(&self) -> u32

Determine a keyCode value for a key.

The keyCode is an implementation specific legacy property of DOM keyboard events.

Specification: https://w3c.github.io/uievents/#dom-keyboardevent-keycode

Trait Implementations

impl Clone for Key

fn clone(&self) -> Key

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Key

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

Formats the value using the given formatter.

impl Default for Key

fn default() -> Key

Returns the “default value” for a type.

impl Display for Key

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

impl Eq for Key

impl From<NamedKey> for Key

fn from(value: NamedKey) -> Key

Converts to this type from the input type.

impl FromStr for Key

type Err = UnrecognizedKeyError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Key, <Key as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for Key

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

where __H: Hasher,

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 Ord for Key

fn cmp(&self, other: &Key) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for Key

fn eq(&self, other: &Key) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Key

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