InputEvent

Struct InputEvent 

Source
#[repr(C)]
pub struct InputEvent { pub sec: i64, pub usec: i64, pub event_type: u16, pub code: u16, pub value: i32, }
Expand description

Miroir #[repr(C)] de struct input_event (24 octets sur LP64).

Champs aux noms kernel conservés (ADR-029, nuance « type miroir »).

Signedness des horodatages. struct input_event embarque un struct timeval { __kernel_time_t tv_sec; __kernel_suseconds_t tv_usec; }. Sur LP64 (x86_64 / aarch64, les deux cibles d’Air), __kernel_time_t et __kernel_suseconds_t sont tous deux long signés : on type donc sec et usec en i64 pour refléter fidèlement l’ABI kernel. La spec family-device.md les notait u64 ; le miroir privilégie la fidélité de l’ABI (la taille — 8 octets — est identique, le #[repr(C)] inchangé).

Fields§

§sec: i64

Secondes de l’horodatage (struct timeval::tv_sec, time_t signé).

§usec: i64

Microsecondes (struct timeval::tv_usec, suseconds_t signé).

§event_type: u16

Type d’événement (EV_KEY, EV_REL, EV_ABS, EV_SYN…).

§code: u16

Code (touche, axe, bouton) dépendant du type.

§value: i32

Valeur (1/0 pour une touche, delta EV_REL, absolu EV_ABS).

Implementations§

Source§

impl InputEvent

Source

pub fn slice_from_bytes(bytes: &[u8]) -> Option<&[InputEvent]>

Réinterprète un buffer d’octets en tranche d’InputEvent (zéro copie).

None si la longueur n’est pas un multiple de size_of::<InputEvent>() ou si l’alignement (8 octets) n’est pas respecté. Utile quand les octets viennent d’ailleurs (io_uring, mmap).
