Role

Enum Role

}
Expand description

The ARIA-style role of a semantic node in the accessibility tree.

This is the one source of truth for role data flowing through RenderTree::collect_semantics() — used both for assistive tech (D099) and, from D107/Phase 25 on, for mapping to real HTML tags (<h1>-<h6>, <a>, <ul>/<li>, …) for SEO/crawler-facing output. Deliberately NOT unified with the separate, richer rosace_a11y::role::Role — that one drives rosace-a11y’s own internal focus-management tree, a different concern (focus navigation, not HTML/SEO structure); merging them would touch already-working, unrelated code for no benefit this phase actually needs. Link/Heading/List/ListItem/Tab/ TabPanel/Radio added here specifically for the HTML mapping Phase 25 needs (a heading’s level and a link’s href live on SemanticNode/ Semantics directly, not on the enum, since they’re per-instance data, not part of what kind of role it is). Radio is distinct from Checkbox — real ARIA/HTML (role="radio" vs role="checkbox") distinguishes mutually-exclusive single-select from independent toggles; approximating one as the other would be wrong, not just imprecise, so it earns its own variant rather than reusing Checkbox.
