Struct ListSizeConstraint

pub struct ListSizeConstraint { /* private fields */ }

A constraint on a list size The list must be composed of a number n of groups of size group_size which means list size must be a multiple of group_size. Moreover, n must be:

• bigger or equal to min_inclusive_group_count
• smaller of equal to max_inclusive_group_count
