Trait Implementations

impl<'bc> Block for Block<'bc>

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>

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 account 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.

impl<'bc> Debug for Block<'bc>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'bc> Eq for Block<'bc>

impl<'bc> PartialEq<Block<'bc>> for Block<'bc>

fn eq(&self, other: &Block<'bc>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Block<'bc>) -> bool

This method tests for !=.
