[−][src]Struct sys_mount::UnmountFlags
Flags which may be specified when unmounting a file system.
Implementations
impl UnmountFlags
[src]
pub const FORCE: UnmountFlags
[src]
Force unmount even if busy. This can cause data loss. (Only for NFS mounts.)
pub const DETACH: UnmountFlags
[src]
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
[src]
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
[src]
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 const fn empty() -> UnmountFlags
[src]
Returns an empty set of flags
pub const fn all() -> UnmountFlags
[src]
Returns the set containing all flags.
pub const fn bits(&self) -> c_int
[src]
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: c_int) -> Option<UnmountFlags>
[src]
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: c_int) -> UnmountFlags
[src]
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: c_int) -> UnmountFlags
[src]
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
pub const fn is_empty(&self) -> bool
[src]
Returns true
if no flags are currently stored.
pub const fn is_all(&self) -> bool
[src]
Returns true
if all flags are currently set.
pub const fn intersects(&self, other: UnmountFlags) -> bool
[src]
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: UnmountFlags) -> bool
[src]
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: UnmountFlags)
[src]
Inserts the specified flags in-place.
pub fn remove(&mut self, other: UnmountFlags)
[src]
Removes the specified flags in-place.
pub fn toggle(&mut self, other: UnmountFlags)
[src]
Toggles the specified flags in-place.
pub fn set(&mut self, other: UnmountFlags, value: bool)
[src]
Inserts or removes the specified flags depending on the passed value.
