Enum MapError 

#[non_exhaustive]
pub enum MapError {
    Unavailable,
    Backend(Box<dyn Error + Send + Sync>),
}

A picture could not be mapped.

Variants (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.

Unavailable

The storage is not readable on the CPU.

Backend(Box<dyn Error + Send + Sync>)

The backend refused. Preserve its concrete error and any location trace instead of formatting them into a message.
