pub fn safe_add(a: i64, b: i64) -> Result<i64, ConsensusError>Expand description
Fast-path addition with overflow checking
Uses manual overflow detection for common cases (both positive values)
which is faster than checked_add for the hot path. Falls back to
checked_add for edge cases.
ยงSafety
This function maintains the same safety guarantees as checked_add,
but with better performance for common cases.
