pub struct MatchCriteria {
    pub src_ip: Option<CidrAddress>,
    pub dst_ip: Option<CidrAddress>,
    pub src_port: Option<PortRange>,
    pub dst_port: Option<PortRange>,

Criteria for matching packets against a firewall rule

Fields

src_ip: Option<CidrAddress>

Source IP with CIDR mask (None = match any)

dst_ip: Option<CidrAddress>

Destination IP with CIDR mask (None = match any)

src_port: Option<PortRange>

Source port range (None = match any)

dst_port: Option<PortRange>

Destination port range (None = match any)

protocol: Protocol

IP protocol (Any = match all protocols)

tcp_flags: Option<TcpFlags>

TCP flags to match (None = don’t check flags)

conn_state: Option<ConntrackState>

Connection tracking state (None = don’t check state)

negate_src: bool

Negate source IP match

negate_dst: bool

Negate destination IP match

Implementations

impl MatchCriteria

pub fn new() -> Self

pub fn with_src_ip(self, cidr: CidrAddress) -> Self

Set source IP CIDR

pub fn with_dst_ip(self, cidr: CidrAddress) -> Self

Set destination IP CIDR

pub fn with_src_port(self, range: PortRange) -> Self

Set source port range

pub fn with_dst_port(self, range: PortRange) -> Self

Set destination port range

pub fn with_protocol(self, proto: Protocol) -> Self

Set protocol

pub fn with_tcp_flags(self, flags: TcpFlags) -> Self

Set TCP flags match

pub fn with_conn_state(self, state: ConntrackState) -> Self

Set connection state match

Trait Implementations

impl Clone for MatchCriteria

fn clone(&self) -> MatchCriteria

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MatchCriteria

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

Formats the value using the given formatter.

impl Default for MatchCriteria

fn default() -> MatchCriteria

Returns the “default value” for a type.
