Expand description
Set of errors which may happen when working with contract headers.
Variants
PreviouslyUsedVersion
Attempt to override an existing or previously existing version with a new header (this is not allowed to ensure immutability of a given version).
assert_eq!(1, Error::PreviouslyUsedVersion as u8);
ContractNotFound
Attempted to disable a contract that does not exist.
assert_eq!(2, Error::ContractNotFound as u8);
GroupAlreadyExists
Attempted to create a user group which already exists (use the update function to change an existing user group).
assert_eq!(3, Error::GroupAlreadyExists as u8);
MaxGroupsExceeded
Attempted to add a new user group which exceeds the allowed maximum number of groups.
assert_eq!(4, Error::MaxGroupsExceeded as u8);
MaxTotalURefsExceeded
Attempted to add a new URef to a group, which resulted in the total number of URefs across all user groups to exceed the allowed maximum.
assert_eq!(5, Error::MaxTotalURefsExceeded as u8);
GroupDoesNotExist
Attempted to remove a URef from a group, which does not exist in the group.
assert_eq!(6, Error::GroupDoesNotExist as u8);
UnableToRemoveURef
Attempted to remove unknown URef from the group.
assert_eq!(7, Error::UnableToRemoveURef as u8);
GroupInUse
Group is use by at least one active contract.
assert_eq!(8, Error::GroupInUse as u8);
URefAlreadyExists
URef already exists in given group.
assert_eq!(9, Error::URefAlreadyExists as u8);
