Represents an SRP client service.

The values in this structure, including the string buffers for the names and the TXT record entries, MUST persist and stay constant after an instance of this structure is passed to OpenThread from otSrpClientAddService() or otSrpClientRemoveService().

The mState, mData, mNext fields are used/managed by OT core only. Their value is ignored when an instance of otSrpClientService is passed in otSrpClientAddService() or otSrpClientRemoveService() or other functions. The caller does not need to set these fields.

The mLease and mKeyLease fields specify the desired lease and key lease intervals for this service. Zero value indicates that the interval is unspecified and then the default lease or key lease intervals from otSrpClientGetLeaseInterval() and otSrpClientGetKeyLeaseInterval() are used for this service. If the key lease interval (whether set explicitly or determined from the default) is shorter than the lease interval for a service, SRP client will re-use the lease interval value for key lease interval as well. For example, if in service mLease is explicitly set to 2 days and mKeyLease is set to zero and default key lease is set to 1 day, then when registering this service, the requested key lease for this service is also set to 2 days.
