Trait pallet_evm::Precompile[−][src]

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

One single precompile used by EVM engine.

Required methods

`pub fn execute( input: &[u8], target_gas: Option<u64>, context: &Context ) -> Result<(ExitSucceed, Vec<u8, Global>, u64), ExitError>`[src]

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(_).
