Trait GasMeter

pub trait GasMeter {
    const MAXIMUM_BASE_GAS: u64;

    // Required method
    fn maximum_dispatch_gas_used_at_most(command: &Command) -> u64;

    // Provided method
    fn maximum_gas_used_at_most(command: &Command) -> u64 { ... }
}

Required Associated Constants

const MAXIMUM_BASE_GAS: u64

All the gas used for submitting a message to Ethereum, minus the cost of dispatching the command within the message

Required Methods

fn maximum_dispatch_gas_used_at_most(command: &Command) -> u64

Measures the maximum amount of gas a command payload will require to dispatch, NOT including validation & verification.

Provided Methods

fn maximum_gas_used_at_most(command: &Command) -> u64

Total gas consumed at most, including verification & dispatch

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
