Zephyr Host State Implementation.

Fields§

§id: i64

Host id.

§network_id: [u8; 32]

Network id hashed.

§transmitter: RefCell<Option<UnboundedSender<Vec<u8>>>>

Transmitter

§result: RefCell<String>

Result of the invocation. Currently this can only be a string.

§latest_close: RefCell<Option<Vec<u8>>>

Latest ledger close meta. This is set as optional as some Zephyr programs might not need the ledger meta.

NB: naming probably needs to change as this is used to just communicate starting input to a program, which could be both:

  • a ledger close meta (state transition) < for ingestors
  • a request body < for functions
§database: RefCell<Database<DB>>

Database implementation.

§ledger: Ledger<L>

Ledger state.

§budget: RefCell<Budget>

Budget implementation.

§entry_point_info: RefCell<InvokedFunctionInfo>

Entry point info.

§context: RefCell<VmContext<DB, L>>

VM context.

§stack: RefCell<Stack>

Host pseudo stack implementation.

§soroban: RefCell<Host>

Wrapper for the Soroban Host Environment
