pub fn calculate_gas(&mut self, value: bool) -> &mut Self {

Whether gas should be calculated while executing. Defaults to `true`.
Determines whether the gas field in the `ExecutionReport` is `None` or `Some`.

During proving, gas is not calculated, so this option has no effect.

Disabling gas calculation will likely speed up execution.
