The flags for CheckpointCreate call

Implementations

impl CheckpointCreateFlags

pub const NONE: Self

no flags

pub const DESTROY_ALL: Self

when creating a new checkpoint, destroy all existing ones.

pub const DELETE_NEW_CONNECTIONS: Self

upon rollback, delete any new connection added after the checkpoint. Since: 1.6.

pub const DISCONNECT_NEW_DEVICES: Self

upon rollback, disconnect any new device appeared after the checkpoint. Since: 1.6.

pub const ALLOW_OVERLAPPING: Self

by default, creating a checkpoint fails if there are already existing checkpoints that reference the same devices. With this flag, creation of such checkpoints is allowed, however, if an older checkpoint that references overlapping devices gets rolled back, it will automatically destroy this checkpoint during rollback. This allows one to create several overlapping checkpoints in parallel, and rollback to them at will. With the special case that rolling back to an older checkpoint will invalidate all overlapping younger checkpoints. This opts-in that the checkpoint can be automatically destroyed by the rollback of an older checkpoint. Since: 1.12.

pub const NO_PRESERVE_EXTERNAL_PORTS: Self

during rollback, by default externally added ports attached to bridge devices are preserved. With this flag, the rollback detaches all external ports. This only has an effect for bridge ports. Before 1.38, this was the default behavior. Since: 1.38.

pub const TRACK_INTERNAL_GLOBAL_DNS: Self

during rollback, by default changes to global DNS via D-BUS interface are preserved. With this flag, the rollback reverts the global DNS changes made via D-Bus interface. Global DNS defined in [global-dns] section of NetworkManager.conf is not impacted by this flag. Since: 1.48.

impl CheckpointCreateFlags

pub const fn empty() -> Self

Get a flags value with all bits unset.

pub const fn all() -> Self

The returned value is exactly the bits set in this flags value.

Convert from a bits value.

This method will return None if any unknown bits are set.

pub const fn from_bits_truncate(bits: u32) -> Self

pub const fn from_bits_retain(bits: u32) -> Self

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<Self>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

Whether all set bits in a source flags value are also set in a target flags value.

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

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

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

The bitwise exclusive-or (^) of the bits in two flags values.

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

Call insert when value is true or remove when value is false.

The bitwise and (&) of the bits in two flags values.

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

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

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

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl CheckpointCreateFlags

pub const fn iter(&self) -> Iter<CheckpointCreateFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<CheckpointCreateFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
