Trait providing access to fields specific to AMM objects in any ledger.

Provided Methods

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

The address of the special account that holds this AMM’s assets.

fn trading_fee(&self) -> Result<Option<u16>>

The percentage fee to be charged for trades against this AMM instance, in units of 1/100,000. The maximum value is 1000, for a 1% fee.

fn lp_token_balance(&self) -> Result<Amount>

The total outstanding balance of liquidity provider tokens from this AMM instance. The holders of these tokens can vote on the AMM’s trading fee in proportion to their holdings, or redeem the tokens for a share of the AMM’s assets which grows with the trading fees collected.

fn asset(&self) -> Result<Issue>

The definition for one of the two assets this AMM holds. In JSON, this is an object with currency and issuer fields.

fn asset2(&self) -> Result<Issue>

The definition for the other asset this AMM holds. In JSON, this is an object with currency and issuer fields.

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

The OwnerNode field (Required).

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

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

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

The index of the ledger that contains the transaction that most recently modified this entry.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
