Backend-agnostic key input kind.

This type is marked as #[non_exhaustive] since more keys may be supported in the future.

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.

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 Default for Key

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Key

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<KeyCode> for Key

Available on crate features crossterm or tuirs-crossterm only.

fn from(code: KeyCode) -> Self

Convert crossterm::event::KeyCode into Key.

impl From<KeyCode> for Key

Available on crate feature termwiz only.

fn from(key: KeyCode) -> Self

Convert termwiz::input::KeyCode into Key.

impl From<MouseButton> for Key

Available on crate features termion or tuirs-termion only.

fn from(button: MouseButton) -> Self

Convert termion::event::MouseButton into Key.

impl From<MouseButtons> for Key

Available on crate feature termwiz only.

fn from(buttons: MouseButtons) -> Self

Convert termwiz::input::MouseButtons into Key.

impl From<MouseEventKind> for Key

Available on crate features crossterm or tuirs-crossterm only.

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,

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.

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
