Struct sys_mount::UnmountFlags [−]
pub struct UnmountFlags { /* fields omitted */ }
Flags which may be specified when unmounting a file system.
Methods
impl UnmountFlags
impl UnmountFlags
pub const FORCE: UnmountFlags
FORCE: UnmountFlags = UnmountFlags{bits: MNT_FORCE,}
Force unmount even if busy. This can cause data loss. (Only for NFS mounts.)
pub const DETACH: UnmountFlags
DETACH: UnmountFlags = UnmountFlags{bits: MNT_DETACH,}
Perform a lazy unmount: make the mount point unavailable for new accesses, and actually perform the unmount when the mount point ceases to be busy.
pub const EXPIRE: UnmountFlags
EXPIRE: UnmountFlags = UnmountFlags{bits: MNT_EXPIRE,}
Mark the mount point as expired. If a mount point is not currently in use, then an initial call to umount2() with this flag fails with the error EAGAIN, but marks the mount point as expired. The mount point remains expired as long as it isn't accessed by any process. A second umount2() call specifying MNT_EXPIRE unmounts an expired mount point. This flag cannot be specified with either MNT_FORCE or MNT_DETACH.
pub const NOFOLLOW: UnmountFlags
NOFOLLOW: UnmountFlags = UnmountFlags{bits: O_NOFOLLOW,}
Don't dereference target if it is a symbolic link. This flag allows security problems to be avoided in set-user-ID-root programs that allow unprivileged users to unmount file systems.
pub fn empty() -> UnmountFlags
pub fn empty() -> UnmountFlags
Returns an empty set of flags.
pub fn all() -> UnmountFlags
pub fn all() -> UnmountFlags
Returns the set containing all flags.
pub fn bits(&self) -> i32
pub fn bits(&self) -> i32
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: i32) -> Option<UnmountFlags>
pub fn from_bits(bits: i32) -> Option<UnmountFlags>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub fn from_bits_truncate(bits: i32) -> UnmountFlags
pub fn from_bits_truncate(bits: i32) -> UnmountFlags
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub fn is_empty(&self) -> bool
pub fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
pub fn is_all(&self) -> bool
pub fn is_all(&self) -> bool
Returns true
if all flags are currently set.
pub fn intersects(&self, other: UnmountFlags) -> bool
pub fn intersects(&self, other: UnmountFlags) -> bool
Returns true
if there are flags common to both self
and other
.
pub fn contains(&self, other: UnmountFlags) -> bool
pub fn contains(&self, other: UnmountFlags) -> bool
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: UnmountFlags)
pub fn insert(&mut self, other: UnmountFlags)
Inserts the specified flags in-place.
pub fn remove(&mut self, other: UnmountFlags)
pub fn remove(&mut self, other: UnmountFlags)
Removes the specified flags in-place.
pub fn toggle(&mut self, other: UnmountFlags)
pub fn toggle(&mut self, other: UnmountFlags)
Toggles the specified flags in-place.
pub fn set(&mut self, other: UnmountFlags, value: bool)
pub fn set(&mut self, other: UnmountFlags, value: bool)
Inserts or removes the specified flags depending on the passed value.
