Implementations

impl RuleMessage

pub fn new() -> Self

Create a new empty rule message.

pub fn family(&self) -> u8

Get the address family.

pub fn is_ipv4(&self) -> bool

Check if this is an IPv4 rule.

pub fn is_ipv6(&self) -> bool

Check if this is an IPv6 rule.

pub fn src_len(&self) -> u8

Get the source prefix length.

pub fn dst_len(&self) -> u8

Get the destination prefix length.

pub fn action(&self) -> FibRuleAction

Get the rule action.

pub fn is_lookup(&self) -> bool

Check if this is a table lookup rule.

pub fn is_blackhole(&self) -> bool

Check if this is a blackhole rule.

pub fn is_unreachable(&self) -> bool

Check if this is an unreachable rule.

pub fn is_prohibit(&self) -> bool

Check if this is a prohibit rule.

pub fn table_id(&self) -> u32

Get the routing table ID.

pub fn is_default(&self) -> bool

Check if this is a default rule (priority 0, 32766, or 32767).

Trait Implementations

impl Clone for RuleMessage

fn clone(&self) -> RuleMessage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RuleMessage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RuleMessage

fn default() -> RuleMessage

Returns the “default value” for a type.

impl FromNetlink for RuleMessage

fn write_dump_header(buf: &mut Vec<u8>)

Write the header required for dump requests. This is appended to the netlink message after the nlmsghdr. Default implementation writes nothing (for messages that don’t need a header).

fn parse(input: &mut &[u8]) -> PResult<Self>

Parse from a mutable byte slice reference. The slice is advanced past the consumed bytes.

fn from_bytes(data: &[u8]) -> Result<Self>

Parse from a complete byte slice.
