Struct PickerDisplay 

pub struct PickerDisplay;

Where the picker UI is drawn. "minibuffer" renders vertico-style: prompt sits on the cmdline row and the candidate list fans above it (TUI) / above the status line (GPUI), keeping the buffer fully visible. "popup" renders a centred overlay floating over the buffer area (terminal-friendly when narrow, common in IDE-style editors). Behaviour is identical between the TUI and GPUI peers so users carry the same muscle memory across them. Future variants ("split", "sidebar") may be added without breaking this key.

Implementations

impl PickerDisplay

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 PickerDisplay

const GROUP_NAME: &'static str = <crate::Picker 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 PickerDisplay

const NAME: &'static str = PickerDisplay

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 = PickerDisplay

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.
