FutexWaiter

air_sys_syscall::io_uring

Struct FutexWaiter 

Source 
pub struct FutexWaiter {
    pub region: MmapRegion,
    pub offset: usize,
    pub expected: u64,
}
Expand description

Un attendu de IoUring::submit_futex_waitv : la région partageable + le décalage du mot futex, et la valeur attendue.

La region est possédée (un clone de la MmapRegion) : elle est la garde de vivacité naturelle — tant que le FutexWaiter (et donc la garde garée dans le slot) vit, la région reste mappée.

Fields§

§region: MmapRegion

Région partageable contenant le mot futex (gardée vivante par le slot).

§offset: usize

Décalage du mot futex dans la région (borné, aligné sur 4).

§expected: u64

Valeur attendue au mot à l’armement.
