    pub deposit_offset: Balance,
    pub creation_slot: Slot,
    pub last_accumulation_slot: Slot,
    pub parent_service: ServiceId,
}

Information concerning a particular service’s state.

This is used in the service_info host-call.

Fields

code_hash: CodeHash

The hash of the code of the service.

balance: Balance

The existing balance of the service.

threshold: Balance

The minimum balance which the service must satisfy.

min_item_gas: UnsignedGas

The minimum amount of gas which must be provided to this service’s accumulate for each work item it must process.

min_memo_gas: UnsignedGas

The minimum amount of gas which must be provided to this service’s accumulate for each incoming transfer it must process.

bytes: u64

The total number of bytes used for data electively held for this service on-chain.

items: u32

The total number of items of data electively held for this service on-chain.

deposit_offset: Balance

Offset of storage footprint only above which a minimum deposit is needed.

creation_slot: Slot

Creation time slot.

last_accumulation_slot: Slot

Most recent accumulation time slot.

parent_service: ServiceId

Parent service identifier.
