source§fn simplify(&mut self) -> bool
fn simplify(&mut self) -> bool
Attempts to simplify the current value. Notionally, this sets the
“high” value to the current value, and the current value to a “halfway
point” between high and low, rounding towards low. Read more
source§fn complicate(&mut self) -> bool
fn complicate(&mut self) -> bool
Attempts to partially undo the last simplification. Notionally, this
sets the “low” value to one plus the current value, and the current
value to a “halfway point” between high and the new low, rounding
towards low. Read more
