Struct EmacsKeysPrefix 

pub struct EmacsKeysPrefix;

The emacs-keys leader prefix — the chord that opens the <C-x> tribute map (docs/dev/architecture/emacs-keys.md). Default <C-x>. Each binding is prefix + suffix, parsed via parse_chord_sequence; a malformed value degrades to an empty tribute (warn, no panic). Live: :set emacs-keys-prefix=… re-pushes the layer.

Implementations

impl EmacsKeysPrefix

pub fn build_spec() -> Option<String>

Build the runtime spec for this declaration. Used by the registry’s self-registration boot path; not generally called by hand. Direct construction of Option<T> is the macro’s internal-only path – consumer code uses config.get_typed::<#name_ident>() to read and config.set_typed::<#name_ident>(...) to write.

Trait Implementations

impl HasGroup for EmacsKeysPrefix

const GROUP_NAME: &'static str = <crate::Editor as ::lattice_config::OptionGroup>::NAME

Group display name ("editor", "lsp", …). The macro pulls this from the group = SomeGroup; directive at the declaration block’s head.

impl OptionDecl for EmacsKeysPrefix

const NAME: &'static str = EmacsKeysPrefix

Public display name. Boundary-facing only – :set <NAME>=…, TOML keys, completion candidates, :describe-option. Internal access is type-driven. The macro derives this from the option’s identifier (with namespace prefix when declared via mode_options!); manually-typed NAMEs are not supported for built-in options.

const DOC: &'static str = EmacsKeysPrefix

Doc string. Shown in :describe-option, the :customize form’s per-row help, and :apropos results.

const CUSTOMIZABLE: bool = true

Customize-visibility flag. true (the default) ⇒ option appears in :set autocomplete + the :customize group view. false ⇒ plugin / engine-internal state, hidden from user surfaces. Equivalent of emacs’s defvar vs defcustom. (See mode-architecture.md §6.5.3.)

type Value = String

The runtime value type. bool, i64, String, plus any domain enum that impls OptionType.

fn default_value() -> Self::Value

Default value. Returned by a function (rather than a const) so non-const-constructible types like String can be defaults.

fn type_id() -> TypeId

where Self: Sized,

TypeId of the declaration type itself. Hot-path key for the registry’s type-driven storage. Default impl works for every concrete impl.
