Enum bson::document::ValueAccessError
source · #[non_exhaustive]pub enum ValueAccessError {
NotPresent,
UnexpectedType,
}
Expand description
Error to indicate that either a value was empty or it contained an unexpected type, for use with the direct getters.
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.
NotPresent
Cannot find the expected field with the specified key
UnexpectedType
Found a Bson value with the specified key, but not with the expected type
