Transaction context.

Fields

protocol: Arc<Protocol>

Low-level access to the underlying Runtime Host Protocol.

consensus_block: &'a LightBlock

Consensus light block.

consensus_state: ConsensusState

Consensus state tree.

runtime_state: &'a mut dyn MKVS

Runtime state.

header: &'a Header

The block header accompanying this transaction.

epoch: EpochTime

Epoch corresponding to the currently processed block.

round_results: &'a RoundResults

Results of processing the previous successful round.

max_messages: u32

The maximum number of messages that can be emitted in this round.

check_only: bool

Flag indicating whether to only perform transaction check rather than running the transaction.
