Trait Implementations

impl Clone for MPToken

fn clone(&self) -> MPToken

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MPToken

impl Debug for MPToken

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

Formats the value using the given formatter.

impl Eq for MPToken

impl LedgerObjectCommonFields for MPToken

fn get_slot_num(&self) -> i32

Returns the slot number (register number) where the ledger object is stored.

fn path(&self) -> LedgerPathBuilder

Starts a nested-field path rooted at this ledger object, read through its slot.

fn get_flags(&self) -> Result<u32>

Retrieves the flags field of the ledger object.

fn get_ledger_entry_type(&self) -> Result<u16>

Retrieves the ledger entry type of the object.

impl MPTokenFields for MPToken

fn account(&self) -> Result<AccountID>

The owner (holder) of these MPTs.

fn mptoken_issuance_id(&self) -> Result<Hash192>

The MPTokenIssuance identifier.

fn mpt_amount(&self) -> Result<Option<u64>>

The amount of tokens currently held by the owner. The minimum is 0 and the maximum is 2^63-1.

fn locked_amount(&self) -> Result<Option<u64>>

The amount of tokens currently locked up (for example, in escrow).

fn owner_node(&self) -> Result<u64>

A hint indicating which page of the owner directory links to this entry, in case the directory consists of multiple pages.

fn previous_txn_id(&self) -> Result<Hash256>

The identifying hash of the transaction that most recently modified this entry.

fn previous_txn_lgr_seq(&self) -> Result<u32>

The sequence of the ledger that contains the transaction that most recently modified this object.

fn confidential_balance_inbox(&self) -> Result<Option<StandardBlob>>

Encrypted inbox balance that receives incoming confidential transfers. Before it can be spent, the holder must merge it into their spending balance using the ConfidentialMPTMergeInbox transaction. Present when the holder has a confidential balance.

fn confidential_balance_spending(&self) -> Result<Option<StandardBlob>>

Encrypted spending balance used to generate proofs for outgoing transactions. Present when the holder has a confidential balance.

fn confidential_balance_version(&self) -> Result<Option<u32>>

Version number that increments each time the spending balance changes. This version is cryptographically bound to ZKPs in outgoing transactions to prevent replay attacks and ensure proof validity. If the version changes between proof generation and submission, the transaction will fail.

fn issuer_encrypted_balance(&self) -> Result<Option<StandardBlob>>

Copy of the holder’s total confidential balance encrypted for the issuer to audit supply. Present when the holder has a confidential balance.

fn auditor_encrypted_balance(&self) -> Result<Option<StandardBlob>>

The holder’s total confidential balance encrypted under the auditor’s key for independent auditing. Only present if an auditor is configured.

fn holder_encryption_key(&self) -> Result<Option<StandardBlob>>

The holder’s ElGamal public key for confidential balances. Present when the holder has a confidential balance.

impl PartialEq for MPToken

fn eq(&self, other: &MPToken) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
