Trait pallet_evm::Precompile

pub trait Precompile {
    fn execute(
        input: &[u8], 
        target_gas: Option<u64>, 
        context: &Context
    ) -> Result<PrecompileOutput, ExitError>;
}

One single precompile used by EVM engine.

Required methods

fn execute(
    input: &[u8],
    target_gas: Option<u64>,
    context: &Context
) -> Result<PrecompileOutput, ExitError>

Try to execute the precompile. Calculate the amount of gas needed with given input and target_gas. Return Ok(status, output, gas_used) if the execution is successful. Otherwise return Err(_).
