Struct MultiTransfer 

Source 
pub struct MultiTransfer<P>(pub P)
where
    P: MultiTransferMarkerArg;
Expand description

A wrapper that forces payments to go via MultiESDTtransfer, even if it wouldn’t be necessary, such as:

  • Just EGLD
  • Single fungible ESDT transfers,
  • Single NFT transfers.

This contrasts with unwrapped PaymentVec, tries to use the simplest possible transfer type.

impl<Env, P> TxPayment<Env> for MultiTransfer<P>
where Env: TxEnv, P: MultiTransferMarkerArg + AsRef<ManagedVec<<Env as TxEnv>::Api, Payment<<Env as TxEnv>::Api>>>,

Source§

fn is_no_payment(&self, _env: &Env) -> bool

Returns true if payment indicates transfer of either non-zero EGLD or ESDT amounts.
Source§

fn perform_transfer_execute_fallible( self, _env: &Env, to: &ManagedAddress<<Env as TxEnv>::Api>, gas_limit: u64, fc: FunctionCall<<Env as TxEnv>::Api>, ) -> Result<(), TransferExecuteFailed>

Transfer-execute calls have different APIs for different payments types. This method selects between them.
Source§

fn perform_transfer_execute_legacy( self, _env: &Env, to: &ManagedAddress<<Env as TxEnv>::Api>, gas_limit: u64, fc: FunctionCall<<Env as TxEnv>::Api>, )

Allows transfer-execute without payment.
Source§

fn with_normalized<From, To, F, R>( self, env: &Env, from: &From, to: To, fc: FunctionCall<<Env as TxEnv>::Api>, f: F, ) -> R
where From: TxFrom<Env>, To: TxToSpecified<Env>, F: FnOnce(&ManagedAddress<<Env as TxEnv>::Api>, &BigUint<<Env as TxEnv>::Api>, FunctionCall<<Env as TxEnv>::Api>) -> R,

Converts an ESDT call to a built-in function call, if necessary.
Source§

fn into_full_payment_data( self, _env: &Env, ) -> FullPaymentData<<Env as TxEnv>::Api>
