ProtectKey

miniextendr_api::protect_pool

Struct ProtectKey 

Source 
pub struct ProtectKey {
    slot: u32,
    generation: u32,
}
Expand description

Generational key for a slot in a ProtectPool.

Contains a slot index and a generation counter. If a slot is released and reused, the old key’s generation won’t match and operations will safely return None or no-op.

8 bytes: 4-byte slot index + 4-byte generation.

Fields§
