Expand description

The accessible role for a Accessible implementation.

Abstract roles are only used as part of the ontology; application developers must not use abstract roles in their code.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
