Enum A11yCapability 

pub enum A11yCapability {
    Opaque,
    Partial,
    Full,
}

What a content surface can expose to the accessibility tree. The single vocabulary all engines/surfaces speak (invariant 3). Ordered worst-to-best so capability can be compared / clamped.

Variants

Opaque

No semantic content the host can expose — a raw GPU surface or an opaque system WebView. The host surfaces this honestly (a labelled region with “contents not inspectable”), never as if it were Self::Full. Default for crate::SurfaceEngine (frame-streaming surfaces are opaque until they bridge their content).

Partial

Some structure available — e.g. a bridged WebView exposing a DOM projection (links / headings / text) but not full ARIA, or a partially-modelled document.

Full

A complete semantic tree (headings, links, roles, text). Default for document crate::Engines: their crate::EngineDocument blocks are the semantic content, so they are accessible by construction.

Implementations

impl A11yCapability

pub fn is_inspectable(self) -> bool
