Enum DataMapError 

#[non_exhaustive]
pub enum DataMapError {
    Unavailable,
    UnknownType,
    Undecodable,
}

Why a data map read has no answer. An entry the map gives no value is Ok(None), not one of these.

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

No data maps are loaded here: a client (data maps are not synced to clients), a server before its world’s data first loads, or a host with no game behind it.

UnknownType

No mod registered the map for the entry’s registry in the current data load (data_map_types).

Undecodable

The entry’s value is not one the map’s DataMap::decode takes.
