Implementations

impl<A> CallValueWrapper<A>

where A: CallValueApi + ErrorApi + ManagedTypeApi,

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 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). Warning, not tested with multi transfer, use all_dct_transfers instead!

pub fn token(&self) -> TokenIdentifier<A>

Returns the call value token identifier of the current call. The identifier is wrapped in a TokenIdentifier object, to hide underlying logic.

A note on implementation: even though the underlying api returns an empty name for MOAX, but the MOAX TokenIdentifier is serialized as MOAX. Warning, not tested with multi transfer, use all_dct_transfers instead!

pub fn dct_token_nonce(&self) -> u64

Returns the nonce of the received DCT token. Will return 0 in case of MOAX or fungible DCT transfer. Warning, not tested with multi transfer, use all_dct_transfers instead!

pub fn dct_token_type(&self) -> DctTokenType

Returns the DCT token type. Will return “Fungible” for MOAX. Warning, not tested with multi transfer, use all_dct_transfers instead!

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

Returns both the call value (either MOAX or DCT) and the token identifier. Especially used in the `#[payable(“*”)] auto-generated snippets. The method might seem redundant, but there is such a hook in Arwen that might be used in this scenario in the future. TODO: replace with multi transfer handling everywhere
