Struct Groups

pub struct Groups(/* private fields */);

Struct implementing handling of groups both as numerical values and as bitmasks.

Implementations

impl Groups

pub fn empty() -> Self

Create an empty set of netlink multicast groups

pub fn new_bitmask(mask: u32) -> Self

Create a new set of groups with a bitmask. Each bit represents a group.

pub fn add_bitmask(&mut self, mask: u32)

Add a new bitmask to the existing group set. Each bit represents a group.

pub fn remove_bitmask(&mut self, mask: u32)

Remove a bitmask from the existing group set. Each bit represents a group and each bit set to 1 will be removed.

pub fn new_groups(groups: &[u32]) -> Self

Create a new set of groups from a list of numerical groups values. This differs from the bitmask representation where the value 3 represents group 3 in this format as opposed to 0x4 in the bitmask format.

pub fn add_groups(&mut self, groups: &[u32])

Add a list of numerical groups values to the set of groups. This differs from the bitmask representation where the value 3 represents group 3 in this format as opposed to 0x4 in the bitmask format.

pub fn remove_groups(&mut self, groups: &[u32])

Remove a list of numerical groups values from the set of groups. This differs from the bitmask representation where the value 3 represents group 3 in this format as opposed to 0x4 in the bitmask format.

pub fn as_bitmask(&self) -> Result<u32, MsgError>

Return the set of groups as a bitmask. The representation of a bitmask is u32.

pub fn as_groups(&self) -> Vec<u32>

Return the set of groups as a vector of group values.

pub fn into_groups(self) -> Vec<u32>

Return the set of groups as a vector of group values.

pub fn is_empty(&self) -> bool

Returns true if no group is set.
