Enum Key 

pub enum Key {
    Char(char),
    Backspace,
    MoveLeft,
    MoveRight,
    WordLeft,
    WordRight,
    LineStart,
    LineEnd,
    Reset,
}

One unit of input fed to the Buffer by the platform capture layer.

Variants

Char(char)

A printable character was typed.

Backspace

The Backspace key — delete the character before the caret.

MoveLeft

Left arrow — move the caret left by one character within the buffer. Buffer contents are unchanged.

MoveRight

Right arrow — move the caret right by one character within the buffer.

WordLeft

Ctrl+Left (word-jump) — move the caret to the start of the previous word (or the start of the current word if the caret sits inside one).

WordRight

Ctrl+Right — move the caret past the end of the next word (or the end of the current word if the caret sits inside one).

LineStart

Home — move the caret to the start of the buffer. (The daemon’s buffer holds at most one line — Enter still resets — so “line start” and “buffer start” coincide.)

LineEnd

End — move the caret to the end of the buffer.

Reset

Anything we can’t track precisely: Up/Down/Tab/Enter/Esc, Page Up/Down, focus change, mouse click, or any Ctrl/Alt/ Super shortcut we haven’t taught the buffer about. After one of these the buffer’s contents and caret are no longer trustworthy, so the buffer clears itself.

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 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.

impl Copy for Key

impl Eq for Key

impl StructuralPartialEq for Key
