Struct Combo 

pub struct Combo {
    pub actions: Vec<KeyAction, COMBO_SIZE>,
    pub output: KeyAction,
    pub layer: Option<u8>,
}

Configuration data for a combo.

A combo triggers an output action when a set of keys are pressed simultaneously. The maximum number of trigger keys is determined by COMBO_SIZE (from constants.rs, generated at build time from keyboard.toml on firmware or fixed upper bound on host). Actions are stored in a Vec — only meaningful keys are present (no KeyAction::No padding).

Note: COMBO_SIZE is a wire-format capacity — on firmware it equals COMBO_MAX_LENGTH (from keyboard.toml), on host it’s a fixed upper bound.

Fields

actions: Vec<KeyAction, COMBO_SIZE>

output: KeyAction

layer: Option<u8>

Implementations

impl Combo

pub fn new<I: IntoIterator<Item = KeyAction>>( actions: I, output: KeyAction, layer: Option<u8>, ) -> Self

Create a new combo from an iterator of key actions.

Actions equal to KeyAction::No are filtered out. If there are more non-No actions than COMBO_SIZE, excess actions are silently dropped.

pub fn empty() -> Self

Get an empty combo.

pub fn size(&self) -> usize

Returns the number of key actions in the combo.

pub fn find_key_action_index(&self, key_action: &KeyAction) -> Option<usize>

Find the index of a key action in the combo.

pub fn contains(&self, key_action: &KeyAction) -> bool

Check whether the combo contains the given key action.
