Expand description
Error type specific to retrieving attributes from the attribute dictionary.
Variants§
AlreadyExists(String)
Attribute being inserted already exists.
TypeMismatch
Fields
Attribute exists but the specified type is inaccurate.
DoesNotExist(String)
Couldn’t find the attribute with the given name and location.
WrongSize
Fields
Given attribute size does not match expected attribute size.
KindMismatchFoundDirect
Trying to access an indirect attribute as a direct attribute or vice versa. Expected an indirect attribute, found a direct attribute.
KindMismatchFoundIndirect
Trying to access an indirect attribute as a direct attribute or vice versa. Expected a direct attribute, found an indirect attribute.
MissingAttributeValueCache
Missing attribute value cache for indirect attributes.
