Enum ExpandDecl 

pub enum ExpandDecl {
    Param(ExpandParamDecl),
    Return(ExpandReturnDecl),
}

Unifies the two boundary decls into one type so an adapter’s expand can expose a single entry point — the boundary-decl peer of its class declarator. Deliberately no impl From<syn::Type> for ExpandDecl — a bare syn::Type alone doesn’t say which direction it describes, so every declaration names its direction via the matching constructor macro: .expand(prebindgen_registry::expand_param!(Summary)...), .expand(prebindgen_registry::expand_return!(Sample)...).

Variants

Param(ExpandParamDecl)

Return(ExpandReturnDecl)
