Struct Chord 

pub struct Chord(/* private fields */);

One to Chord::MAX_LEN combos pressed in sequence (g g, Ctrl+x Ctrl+s).

Implementations

impl Chord

pub const MAX_LEN: usize = 4

Longest supported chord.

pub fn single(combo: KeyCombo) -> Self

A one-combo chord.

pub fn new(combos: Vec<KeyCombo>) -> Result<Self, KeyParseError>

Build a chord from combos (1..=Chord::MAX_LEN).

pub fn parse(s: &str) -> Result<Self, KeyParseError>

Parse a whitespace-separated chord such as "g g" or "Ctrl+x Ctrl+s".

pub fn combos(&self) -> &[KeyCombo]

The combos in order.

pub fn len(&self) -> usize

Number of combos.

pub fn is_empty(&self) -> bool

Never true for a chord built through the constructors; provided for API completeness.

pub fn is_prefix_of(&self, other: &Self) -> bool

Whether this chord is a strict prefix of other (g of g g).
