Struct multiversx_chain_vm::tx_mock::TxContextRef

pub struct TxContextRef(/* private fields */);

The VM API implementation based on a blockchain mock written in Rust. Implemented as a smart pointer to a TxContext structure, which tracks a blockchain transaction.

Implementations

impl TxContextRef

pub fn new(tx_context_arc: Arc<TxContext>) -> Self

pub fn new_from_static() -> Self

pub fn dummy() -> Self

pub fn into_blockchain_updates(self) -> BlockchainUpdate

pub fn into_tx_result(self) -> TxResult

Consumes the current API and returns the contained output. Should be called at the end of a tx execution. Will fail if any other references to the tx context survive, this must be the last.

pub fn replace_tx_result_with_error(self, tx_panic: TxPanic)

The current method for signalling that the current execution is failed, and with what error.

Note: does not terminate execution or panic, that is handled separately.
