Implementations

impl<A> CallValueWrapper<A>

where A: CallValueApi + ErrorApi + ManagedTypeApi,

pub fn new() -> Self

pub fn moax_value(&self) -> BigUint<A>

Retrieves the MOAX call value from the VM. Will return 0 in case of an DCT transfer (cannot have both MOAX and DCT transfer simultaneously).

pub fn all_dct_transfers(&self) -> ManagedVec<A, DctTokenPayment<A>>

Returns all DCT transfers that accompany this SC call. Will return 0 results if nothing was transfered, or just MOAX. Fully managed underlying types, very efficient.

pub fn multi_dct<const N: usize>(&self) -> [DctTokenPayment<A>; N]

Verify and casts the received multi DCT transfer in to an array.

Can be used to extract all payments in one line like this:

let [payment_a, payment_b, payment_c] = self.call_value().multi_dct();.

pub fn single_dct(&self) -> DctTokenPayment<A>

Expects precisely one DCT token transfer, fungible or not.

Will return the received DCT payment.

The amount cannot be 0, since that would not qualify as an DCT transfer.

pub fn single_fungible_dct(&self) -> (TokenIdentifier<A>, BigUint<A>)

Expects precisely one fungible DCT token transfer.

Returns the token ID and the amount for fungible DCT transfers.

The amount cannot be 0, since that would not qualify as an DCT transfer.

pub fn dct_value(&self) -> BigUint<A>

Retrieves the DCT call value from the VM. Will return 0 in case of an MOAX transfer (cannot have both MOAX and DCT transfer simultaneously).

pub fn moax_or_single_dct(&self) -> MoaxOrDctTokenPayment<A>

Accepts and returns either an MOAX payment, or a single DCT token.

Will halt execution if more than one DCT transfer was received.

In case no transfer of value happen, it will return a payment of 0 MOAX.

pub fn moax_or_single_fungible_dct( &self ) -> (MoaxOrDctTokenIdentifier<A>, BigUint<A>)

Accepts and returns either an MOAX payment, or a single fungible DCT token.

Will halt execution if more than one DCT transfer was received, or if the received DCT is non- or semi-fungible.

Works similar to moax_or_single_dct, but checks the nonce to be 0 and returns a tuple of just token identifier and amount, for convenience.

In case no transfer of value happen, it will return a payment of 0 MOAX.
