FixedSlotTarget

Enum FixedSlotTarget 

Source
pub enum FixedSlotTarget {
    Index(u32),
    Alloc,
}
Expand description

Cible d’un slot pour une variante « direct » : indice précis, ou auto-allocation par le kernel.

FixedSlotTarget::Alloc est un enum typé, jamais la sentinelle kernel IORING_FILE_INDEX_ALLOC (~0U) exposée (ADR-021 conv. 1).

Variants§

§

Index(u32)

Slot précis (l’indice exact dans la table de FD fixes).

§

Alloc

Le kernel choisit un slot libre (dans la plage d’set_alloc_range) et le rend dans cqe->res (Completion::allocated_slot) ; -ENFILE si plein.
