Struct ringui::enum_set::EnumSet

pub struct EnumSet<E> { /* fields omitted */ }

[−] Expand description

A specialized set implementation to use enum types.

It is a logic error for an item to be modified in such a way that the transformation of the item to or from a usize, as determined by the CLike trait, changes while the item is in the set. This is normally only possible through Cell, RefCell, global state, I/O, or unsafe code.
