[−][src]Struct ethereumvm::BlockhashState
A struct that manages the current blockhash state for one EVM.
Methods
impl BlockhashState
[src]
pub fn require(&self, number: U256) -> Result<(), RequireError>
[src]
Require a blockhash to be existed. If not, requires a
RequireError
.
pub fn commit(&mut self, number: U256, hash: H256) -> Result<(), CommitError>
[src]
Commit a new blockhash. Blockhashes are immutable so the client should be able to use this for other concurrently running EVMs.
pub fn get(&self, number: U256) -> Result<H256, RequireError>
[src]
Get a blockhash by its number.
