[−][src]Trait pallet_evm::precompiles::Precompiles
Custom precompiles to be used by EVM engine.
Required methods
pub fn execute(
address: H160,
input: &[u8],
target_gas: Option<usize>
) -> Option<Result<(ExitSucceed, Vec<u8>, usize), ExitError>>[src]
address: H160,
input: &[u8],
target_gas: Option<usize>
) -> Option<Result<(ExitSucceed, Vec<u8>, usize), ExitError>>
Try to execute the code address as precompile. If the code address is not
a precompile or the precompile is not yet available, return None.
Otherwise, calculate the amount of gas needed with given input and
target_gas. Return Some(Ok(status, output, gas_used)) if the execution
is successful. Otherwise return Some(Err(_)).
