Struct ShrinkFastGrowSlow 

pub struct ShrinkFastGrowSlow { /* private fields */ }

FairShare’s division, applied asymmetrically: a cut lands at once, an increase is ramped at most step units per interval. The safety shape of a shared power or bandwidth budget — a holder must never be granted more than the budget can carry, so reductions cannot wait, while a holder drawing more can wait for the others to have backed off.
