Struct OptionGroupMetadata 

pub struct OptionGroupMetadata {
    pub name: &'static str,
    pub doc: &'static str,
    pub type_id: fn() -> TypeId,
}

Metadata captured at macro expansion for one group. Submitted to the GROUP_DECLS distributed slice; the registry’s startup loader walks the slice to validate uniqueness and build the &str → TypeId lookup table.

Fields

name: &'static str

The group’s OptionGroup::NAME — the :customize <name> key.

doc: &'static str

The group’s OptionGroup::DOC.

type_id: fn() -> TypeId

TypeId::of::<G> for the group type, held as a function pointer so the whole struct stays const-constructible; call it to get the TypeId.

Implementations

impl OptionGroupMetadata

pub const fn for_group<G: OptionGroup>() -> Self

Capture G’s name, doc and type id. const so the crate::groups! expansion can build the GROUP_DECLS entry in a static.

Examples

use lattice_config::{Editor, OptionGroup, OptionGroupMetadata};

const META: OptionGroupMetadata = OptionGroupMetadata::for_group::<Editor>();
assert_eq!(META.name, "editor");
assert_eq!((META.type_id)(), std::any::TypeId::of::<Editor>());
assert_eq!(META.doc, Editor::DOC);
