Enum Key 

#[non_exhaustive]
pub enum Key {
    R,
    X,
    Y,
    Z,
    Up,
    Down,
    Left,
    Right,
    Plus,
    Minus,
    Escape,
    Char(char),
}

Platform-independent key identifier.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

R

Reset.

X

X axis.

Y

Y axis.

Z

Z axis.

Up

Arrow up.

Down

Arrow down.

Left

Arrow left.

Right

Arrow right.

Plus

Zoom in / increase.

Minus

Zoom out / decrease.

Escape

Cancel / exit.

Char(char)

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

Formats the value using the given formatter.

impl Hash for Key

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 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.
