Implementations

impl CloneFlags

pub const CLONE_VM: CloneFlags

The calling process and the child process run in the same memory space.

pub const CLONE_FS: CloneFlags

The caller and the child process share the same filesystem information.

pub const CLONE_FILES: CloneFlags

The calling process and the child process share the same file descriptor table.

pub const CLONE_SIGHAND: CloneFlags

The calling process and the child process share the same table of signal handlers.

pub const CLONE_PTRACE: CloneFlags

If the calling process is being traced, then trace the child also.

pub const CLONE_VFORK: CloneFlags

The execution of the calling process is suspended until the child releases its virtual memory resources via a call to execve(2) or _exit(2) (as with vfork(2)).

pub const CLONE_PARENT: CloneFlags

The parent of the new child (as returned by getppid(2)) will be the same as that of the calling process.

pub const CLONE_THREAD: CloneFlags

The child is placed in the same thread group as the calling process.

pub const CLONE_NEWNS: CloneFlags

The cloned child is started in a new mount namespace.

pub const CLONE_SYSVSEM: CloneFlags

The child and the calling process share a single list of System V semaphore adjustment values

pub const CLONE_DETACHED: CloneFlags

👎Deprecated since 0.23.0:

Deprecated by Linux 2.6.2

Unused since Linux 2.6.2

pub const CLONE_UNTRACED: CloneFlags

A tracing process cannot force CLONE_PTRACE on this child process.

pub const CLONE_NEWCGROUP: CloneFlags

Create the process in a new cgroup namespace.

pub const CLONE_NEWUTS: CloneFlags

Create the process in a new UTS namespace.

pub const CLONE_NEWIPC: CloneFlags

Create the process in a new IPC namespace.

pub const CLONE_NEWUSER: CloneFlags

Create the process in a new user namespace.

pub const CLONE_NEWPID: CloneFlags

Create the process in a new PID namespace.

pub const CLONE_NEWNET: CloneFlags

Create the process in a new network namespace.

pub const CLONE_IO: CloneFlags

The new process shares an I/O context with the calling process.

pub const fn empty() -> CloneFlags

Returns an empty set of flags.

pub const fn all() -> CloneFlags

Returns the set containing all flags.

pub const fn bits(&self) -> i32

Returns the raw value of the flags currently stored.

pub const fn from_bits(bits: i32) -> Option<CloneFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: i32) -> CloneFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: i32) -> CloneFlags

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

Safety

The caller of the bitflags! macro can chose to allow or disallow extra bits for their bitflags type.

The caller of from_bits_unchecked() has to ensure that all bits correspond to a defined flag or that extra bits are valid for this bitflags type.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: CloneFlags) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: CloneFlags) -> bool

Returns true if all of the flags in other are contained within self.

pub fn insert(&mut self, other: CloneFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: CloneFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: CloneFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: CloneFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.

pub const fn intersection(self, other: CloneFlags) -> CloneFlags

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

pub const fn union(self, other: CloneFlags) -> CloneFlags

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both (see Self::symmetric_difference if that is undesirable).

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

pub const fn difference(self, other: CloneFlags) -> CloneFlags

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.

pub const fn symmetric_difference(self, other: CloneFlags) -> CloneFlags

Returns the symmetric difference between the flags in self and other.

Specifically, the returned set contains the flags present which are present in self or other, but that are not present in both. Equivalently, it contains the flags present in exactly one of the sets self and other.

This is equivalent to using the ^ operator (e.g. ops::BitXor), as in flags ^ other.

pub const fn complement(self) -> CloneFlags

Returns the complement of this set of flags.

Specifically, the returned set contains all the flags which are not set in self, but which are allowed for this type.

Alternatively, it can be thought of as the set difference between Self::all() and self (e.g. Self::all() - self)

This is equivalent to using the ! operator (e.g. ops::Not), as in !flags.
