pub struct SequenceNumber(/* private fields */);
Expand description
A numeric type that can represent an infinite ordered sequence.
It uses wrapping arithmetic to make sure we never run out of numbers. (2**64 should be enough for anyone, but it’s easy enough just to make it wrap.) Internally it uses a signed counter so that we can compare values via a subtraction. For example, suppose we’ve just overflowed from i64::MAX to i64::MIN. (i64::MAX.wrapping_sub(i64::MIN)) is -1, which tells us that i64::MAX comes before i64::MIN in the sequence.
