Struct ArenaSeed 

pub struct ArenaSeed<T> {
    pub slots: Vec<(u32, Option<T>)>,
    pub free: Vec<u32>,
}

Per-slot (generation, value) plus the free list. Empty slots keep their generation: reuse bumps it, and a replay that skipped them would hand out different ids for later inserts.

Fields

slots: Vec<(u32, Option<T>)>

free: Vec<u32>
