Implementations

impl ArrowDirection

pub fn from_key(vk: VirtualKeyCode, ctrl: bool) -> Option<Self>

Map a VirtualKeyCode plus the ctrl modifier into an ArrowDirection. Returns None if the key is not a navigation key.

pub fn to_selection(self, ctrl: bool) -> (SelectionDirection, SelectionStep)

Convert to a (SelectionDirection, SelectionStep) pair for the selection-op interpreter. ctrl upgrades arrow keys to word jumps.

Trait Implementations

impl Clone for ArrowDirection

fn clone(&self) -> ArrowDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArrowDirection

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

Formats the value using the given formatter.

impl Hash for ArrowDirection

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 ArrowDirection

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