| bool | empty () const |
| Check whether the storage is empty. | |
| std::span< const std::byte > | as_bytes () const |
| Return a read-only view of all exposed bytes. | |

Static Public Member Functions | |
| static ReadOnlyStorageView | deserialize (std::span< const std::byte > &data) |
Deserialize a size-prefixed view and advance data. | |
A non-owning, read-only view of a byte sequence.
The caller must keep the backing storage alive and must not resize it while this view or a view derived from it is in use.

inlinestatic |
Deserialize a size-prefixed view and advance data.
| std::invalid_argument | if the size prefix or payload is truncated. |
