Struct UiInactivePaneOpacity 

pub struct UiInactivePaneOpacity;

Opacity of the buffer content in inactive panes, as a percentage in [0, 100]. Renderers that support alpha blending (GPUI) apply this when UiDimInactive is true; the TUI peer ignores it (terminal cells don’t have a true alpha channel — TUI uses its Modifier::DIM instead).

Default 50 (0.5 alpha) matches the contrast users see from terminal DIM mode in mainstream fonts. 100 disables the dim (same as :set ui.dim_inactive=false); 0 would hide inactive panes entirely so the validator clamps the lower bound at the option layer, not the renderer.

Implementations

impl UiInactivePaneOpacity

pub fn build_spec() -> Option<i64>

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 UiInactivePaneOpacity

const GROUP_NAME: &'static str = <lattice_config::Appearance 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 UiInactivePaneOpacity

const NAME: &'static str = UiInactivePaneOpacity

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 = UiInactivePaneOpacity

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 = i64

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.
