Struct Evaluated 

#[non_exhaustive]
pub struct Evaluated<T> {
    pub value: T,
    pub ops: Option<u64>,
}

What an evaluation returns: the value and what it cost.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

value: T

The result.

ops: Option<u64>

Operations the evaluation spent: Some when the budget feature is on (zero for a folded constant), None otherwise.
