Struct LeaderKeyProvider 

pub struct LeaderKeyProvider { /* private fields */ }

Provider for the leader key notation.

Personality modules call set during init() to declare their leader key (e.g., "<Space>" for vim). Bootstrap calls get after all modules have loaded and expands <leader> in keybinding strings.

The stored value is &'static str because all call sites are personality module init() methods passing compile-time string literals. This matches the KeybindingRegistration.keys lifetime requirement.

If multiple personality modules are loaded, the last writer wins and a warning should be logged by the caller.

Implementations

impl LeaderKeyProvider

pub const fn new() -> Self

Create a new empty provider.

pub fn set(&self, key: &'static str) -> Option<&'static str>

Set the leader key notation. Called by personality modules during init().

The key parameter is a key notation string (e.g., "<Space>") that will replace <leader> tokens in keybinding key strings.

Returns the previous notation if one was already set.

pub fn get(&self) -> Option<&'static str>

Get the registered leader key notation, if any.

pub fn expand(&self, keys: &str) -> String

Expand <leader> tokens in a key string using the stored notation.

Returns the original string (owned) if no leader key is registered or if the input contains no <leader> token.
