Struct ModeRegistry 

pub struct ModeRegistry { /* private fields */ }

Registry for buffer modes

Manages all available modes and provides lookup functionality with inheritance.

Implementations

impl ModeRegistry

pub fn new() -> Self

Create a new mode registry with built-in modes

pub fn register(&mut self, mode: BufferMode)

Register a new mode

pub fn get(&self, name: &str) -> Option<&BufferMode>

Get a mode by name

pub fn resolve_keybinding( &self, mode_name: &str, code: KeyCode, modifiers: KeyModifiers, ) -> Option<String>

Resolve a keybinding for a mode, following inheritance chain

Returns the command name if a binding is found in this mode or any parent.

pub fn is_read_only(&self, mode_name: &str) -> bool

Check if a mode is read-only (checking inheritance)

pub fn is_chord_prefix( &self, mode_name: &str, chord_state: &[(KeyCode, KeyModifiers)], code: KeyCode, modifiers: KeyModifiers, ) -> bool

Check if a key sequence could be the start of a chord in this mode

This is used to determine if we should wait for more keys before deciding what action to take.

pub fn resolve_chord_keybinding( &self, mode_name: &str, chord_state: &[(KeyCode, KeyModifiers)], code: KeyCode, modifiers: KeyModifiers, ) -> Option<String>

Resolve a chord keybinding (multi-key sequence) for a mode

Returns the command name if the full sequence matches a chord binding.

pub fn list_modes(&self) -> Vec<String>

List all registered mode names

pub fn has_mode(&self, name: &str) -> bool

Check if a mode exists

pub fn get_all_keybindings( &self, mode_name: &str, ) -> HashMap<(KeyCode, KeyModifiers), String>

Get all keybindings for a mode (including inherited ones)

Returns bindings from most specific (this mode) to least specific (root parent). Later bindings override earlier ones.

Trait Implementations

impl Clone for ModeRegistry

fn clone(&self) -> ModeRegistry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ModeRegistry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ModeRegistry

fn default() -> Self

Returns the “default value” for a type.
