Required Methods

fn name(&self) -> &str

Function name corresponding the builtin function implementation.

Currently not used.

fn execute<F>( &self, tx_input: TxInput, tx_cache: TxCache, vm: &BlockchainVMRef, lambda: F, ) -> (TxResult, BlockchainUpdate)

where F: FnOnce(),

Executes builtin function for the givn TxInput and with access to the underlying contracts states via the TxCache.

A few builtin functions (the ones transferring DCDT) can also call the VM after they finish, so they are given the extra reference to the VM and a lambda closure to execute on the VM

Provided Methods

fn extract_dcdt_transfers( &self, tx_input: &TxInput, ) -> BuiltinFunctionDcdtTransferInfo

Extracts data relating DCDT transfers handled by the builtin function, if applicable.
