DirFd

Enum DirFd 

Source
pub enum DirFd<'fd> {
    Cwd,
    Fd(BorrowedFd<'fd>),
}
Expand description

Base d’un appel *at (cf. ADR-021 convention 1).

Remplace la sentinelle kernel AT_FDCWD (-100) par une variante Cwd typée. Air exige une base explicite sur toutes les opérations filesystem — pas de dépendance implicite au cwd global du processus.

§Examples

use air_sys_types::fs::DirFd;
// Ouvrir un fichier par rapport au répertoire courant
let _dirfd = DirFd::Cwd;

Variants§

§

Cwd

Répertoire courant du processus (équivalent à AT_FDCWD).

§

Fd(BorrowedFd<'fd>)

FD d’un répertoire ouvert (accès relatif à ce répertoire).
