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

Trait Implementations

impl<DB: Clone + ZephyrDatabase, L: Clone + LedgerStateRead> Clone for HostImpl<DB, L>

fn clone(&self) -> HostImpl<DB, L>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
