FundsChange

struct FundsChange
{
	Amount m_Amount;
	AssetID m_Aid;
	uint8_t m_Consume;
};

Denotes the amount and the asset type that is supposed to be locked or released when the appropriate contract method is invoked. Used by the app shader as a parameter to GenerateKernel function.

• m_Amount - the amount
• m_Aid - asset ID. Set 0 for beams.
• m_Consume
  • non-zero if this amount is supposed to be spent by the user (i.e. locked by the contract)
  • 0 if this amount is supposed to be received by the user (i.e. released by the contract)

Example

FundsChange fc;
fc.m_Amount = 5;
fc.m_Aid = 0;
fc.m_Consume = 1;

// Generate kernel for locking 5 beams by the contract with contract id cid
// Note: s_iMethod and cid are defined before
Env::GenerateKernel(&cid, s_iMethod, nullptr, 0, &fc, 1, nullptr, 0, "deposit to contract", 0);
