Transaction Metadata Refer to the hashing documentation for information on how it should be hashed.

Fields

submitter_info: Option<SubmitterInfo>

Required

synchronizer_id: String

Required

mediator_group: u32

Required

transaction_uuid: String

Required

preparation_time: u64

Required

input_contracts: Vec<InputContract>

Not populated if the transaction has no input contracts

Optional: can be empty

min_ledger_effective_time: Option<u64>

Optional

max_ledger_effective_time: Option<u64>

Optional

max_record_time: Option<u64>

Maximum timestamp at which the transaction can be recorded onto the ledger via the synchronizer synchronizer_id. If submitted after it will be rejected even if otherwise valid, in which case it needs to be prepared and signed again with a new valid max_record_time. Set max_record_time in the PreparedTransactionRequest to get this field set accordingly

Optional

global_key_mapping: Vec<GlobalKeyMappingEntry>

👎Deprecated

This fields is deprecated and will always be empty. Keys and associated contracts are already present and signed within the transaction nodes where they’re used

Optional: can be empty

Implementations

impl Metadata

pub fn min_ledger_effective_time(&self) -> u64

Returns the value of min_ledger_effective_time, or the default value if min_ledger_effective_time is unset.

pub fn max_ledger_effective_time(&self) -> u64

Returns the value of max_ledger_effective_time, or the default value if max_ledger_effective_time is unset.

pub fn max_record_time(&self) -> u64

Returns the value of max_record_time, or the default value if max_record_time is unset.

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Metadata

fn default() -> Metadata

Returns the “default value” for a type.

impl Message for Metadata
