PosixAccess

Owns one POSIX read/write/execute mode-bit group. This snapshot allocates nothing, retains no resource and grants no access by itself. Execute means traversal for directories. ACLs, mount policy and caller identity can alter effective access. Shared mutation requires synchronization.

PosixAccess.CanWrite

pub CanWrite: bool;

Reported write bit, not an effective-access promise.

PosixAccess.CanExecute

pub CanExecute: bool;
