Struct ContractId

pub struct ContractId(/* private fields */);

A contract-id used to itentify different SmartContracts in the borderless-ecosystem.

These ids are version 8 uuids, where the first four bits of the uuid are set to 0xc, to indicate that it is a contract-id and not another uuid based id.

Example:

cfc23cb3-f447-8107-8f93-9bfb8e1d157d

All uuid-based ids used in the borderless-ecosystem have a different prefix, based on what the id is used for. This mechanism ensures that you cannot mistake a contract-id for e.g. a process-id and vice versa. Even if you convert the contract-id back into a uuid and the result into a process-id, the results are different.

The implementation of the IDs is compliant with RFC9562, as we utilize standard version 8 uuids.
