    fn family_name(&self) -> &str;
    fn family_versions(&self) -> &[String];

Required Methods

TransactionHandler that defines the business logic for a new transaction family. The family_name, family_versions, and namespaces functions are used by the processor to route processing requests to the handler. family_name should return the name of the transaction family that this handler can process, e.g. “intkey”

family_versions should return a list of versions this transaction family handler can process, e.g. [“1.0”]

Apply is the single method where all the business logic for a transaction family is defined. The method will be called by the transaction processor upon receiving a TpProcessRequest that the handler understands and will pass in the TpProcessRequest and an initialized instance of the Context type.
