    { ... }
}

Provided methods

fn into_typed<'de, T>(self) -> Result<T, DeserializationError> where
    T: Deserialize<'de>,

The generic implementation of this method is based on to-be-provided implementations of the target-type-specific trait DbValueInto.

Errors

DeserializationError if the value cannot be converted into the target type.
