Required methods
fn height(&self) -> u64
Returns the height of this block.
fn transact(
&mut self,
caller: Address,
callee: Address,
payer: Address,
value: u128,
input: &[u8],
gas: u64,
gas_price: u64
) -> Box<dyn Receipt>
&mut self,
caller: Address,
callee: Address,
payer: Address,
value: u128,
input: &[u8],
gas: u64,
gas_price: u64
) -> Box<dyn Receipt>
Executes a RPC to callee
with provided input
and gas
computational resources.
value
tokens will be transferred from the caller
to the callee
.
The caller
is charged gas * gas_price
for the computation.
A transaction that aborts (panics) will have its changes rolled back.
This transact
should be called by an Externally Owned Account (EOA).
fn code_at(&self, addr: &Address) -> Option<&[u8]>
Returns the bytecode stored at addr
or None
if the account does not exist.
fn account_meta_at(&self, addr: &Address) -> Option<AccountMeta>
Returns the metadata of the account stored at addr
, or
None
if the account does not exist.
fn state_at(&self, addr: &Address) -> Option<&dyn KVStore>
Returns the state of the acount at addr
, if it exists.
fn events(&self) -> Vec<&Event>
Returns the events emitted during the course of this block.
fn receipts(&self) -> Vec<&dyn Receipt>
Returns the receipts of transactions executed in this block.
