Struct U128CurrencyToVote

pub struct U128CurrencyToVote;

An implementation of CurrencyToVote tailored for chain’s that have a balance type of u128.

The factor is the (total_issuance / u64::MAX).max(1), represented as u64. Let’s look at the important cases:

If the chain’s total issuance is less than u64::MAX, this will always be 1, which means that the factor will not have any effect. In this case, any account’s balance is also less. Thus, both of the conversions are basically an as; Any balance can fit in u64.

If the chain’s total issuance is more than 2*u64::MAX, then a factor might be multiplied and divided upon conversion.
