UTIME_NOW	Re-export UTIME_NOW and UTIME_OMIT.
UTIME_OMIT	Re-export UTIME_NOW and UTIME_OMIT.

Traits

DirEntryExt	Re-export types common to Posix-ish platforms.
FileExt	Re-export types common to Posix-ish platforms.
FileTypeExt	Re-export types common to Posix-ish platforms.
MetadataExt	Re-export types common to Posix-ish platforms.
OpenOptionsExt	Re-export types common to Posix-ish platforms.

Functions

accessat	faccessat(dirfd, path, access, flags)
chmodat	fchmodat(dirfd, path, mode, 0)
copy_file_range	copy_file_range(fd_in, off_in, fd_out, off_out, len, 0)
cwd	Return a “file” which holds a handle which refers to the process current directory (AT_FDCWD). It is a ManuallyDrop, however the caller should not drop it explicitly, as it refers to an ambient authority rather than an open resource.
fadvise	posix_fadvise(fd, offset, len, advice)
fchmod	fchmod(fd).
fcntl_get_seals	fcntl(fd, F_GET_SEALS)
fcntl_getfd	fcntl(fd, F_GETFD)
fcntl_getfl	fcntl(fd, F_GETFL)
fcntl_setfd	fcntl(fd, F_SETFD, flags)
fcntl_setfl	fcntl(fd, F_SETFL, flags)
fstatfs	fstatfs(fd)
futimens	futimens(fd, times)
is_file_read_write	fcntl(fd, F_GETFL) & O_ACCMODE. Returns a pair of booleans indicating whether the file descriptor is readable and/or writeable, respectively. This is only reliable on files; for example, it doesn’t reflect whether sockets have been shut down; for general I/O handle support, use crate::io::is_read_write.
linkat	linkat(old_dirfd, old_path, new_dirfd, new_path, flags)
major	major(dev)
makedev	makedev(maj, min)
memfd_create	memfd_create(path, flags)
minor	minor(dev)
mkdirat	mkdirat(fd, path, mode)
openat	openat(dirfd, path, oflags, mode)
openat2	openat2(dirfd, path, OpenHow { oflags, mode, resolve }, sizeof(OpenHow))
posix_fallocate	posix_fallocate(fd, offset, len)
readlinkat	readlinkat(fd, path)
renameat	renameat(old_dirfd, old_path, new_dirfd, new_path)
seek	lseek(fd, offset, whence)
statat	fstatat(dirfd, path, flags)
statx	statx(dirfd, path, flags, mask, statxbuf). Note that this isn’t available on older Linux; returns ENOSYS in that case.
symlinkat	symlinkat(old_dirfd, old_path, new_dirfd, new_path)
tell	lseek(fd, 0, SEEK_CUR)
unlinkat	unlinkat(fd, path, flags)
utimensat	utimensat(dirfd, path, times, flags)

Type Definitions

FsWord	Re-export __fsword_t.
RawMode	Re-export mode_t.
Stat	Re-export stat (or stat64 where applicable).
StatFs	Re-export stat (or stat64 where applicable).
Statx	Re-export statx. Only available on Linux with GLIBC for now.
