pub struct KeyTableStack { /* private fields */ }

A stack of active key tables

Implementations

impl KeyTableStack

pub fn new(default_table: KeyTable) -> Self

Create a new key table stack with a default table

pub fn push(&mut self, activation: KeyTableActivation)

Push a new key table activation onto the stack

pub fn pop(&mut self) -> Option<KeyTableActivation>

Pop the top key table from the stack

pub fn current(&self) -> Option<&KeyTableActivation>

Get the current (top) key table activation

pub fn current_name(&self) -> &str

Get the name of the current key table, or “default” if stack is empty

pub fn clear(&mut self)

Clear the entire stack

pub fn is_empty(&self) -> bool

Check if the stack is empty

pub fn len(&self) -> usize

Get the number of tables on the stack (not including default)

pub fn resolve(&self, combo: &KeyCombo) -> Option<&KeyAction>

Resolve a key combination by searching the stack from top to bottom

Returns the action if found, None otherwise

pub fn handle_key(&mut self, combo: KeyCombo, now: Instant) -> Option<KeyAction>

Handle a key press, resolving it and managing one-shot/timeout behavior

Returns the action if found, None otherwise

pub fn next_timeout(&self) -> Option<Instant>

Check if any tables have timeouts and return the earliest timeout

pub fn default_table(&self) -> &KeyTable

Get a reference to the default table

pub fn default_table_mut(&mut self) -> &mut KeyTable

Get a mutable reference to the default table
