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 copy 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>

Formats the value using the given formatter.

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 PartialEq for Key

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