Trait pui::runtime::IdAlloc

pub unsafe trait IdAlloc {
    type Id: Copy + Eq;
    pub fn alloc(&mut self) -> Self::Id;
    pub fn try_alloc(&mut self) -> Option<Self::Id>;
}

A id_alloc that allocates new ids

Safety

two equal ids may never exist together on the same thread

This implies that IdAlloc::*next() may never repeat an id on the same thread, and if it can repeat itself on different threads then Self: !Send + !Sync and Self::Id:: !Send + !Sync.

Associated Types
