Expand description

The criteria that a packet must match for a rule to be applied.

Each field is optional, and will only be checked if provided. An unset field will be considered to match any packet. (An entirely empty table would match every packet.) Another way to think of the matching criteria for a given rule is as an AND of every provided matcher.

Some matchers are only available in certain contexts. For example, the in_interface is not available in the EGRESS hook. If a matcher is provided that is not available in the context in which the rule is installed, the installation will fail with an error.

Fields§

§in_interface: Option<InterfaceMatcher>

The interface on which the packet entered the stack.

Only available in INGRESS, LOCAL_INGRESS, and FORWARDING.

§out_interface: Option<InterfaceMatcher>

The interface through which the packet exits the stack.

Only available in FORWARDING, LOCAL_EGRESS, and EGRESS.

§src_addr: Option<AddressMatcher>

Matcher for the source IP address.

§dst_addr: Option<AddressMatcher>

Matcher for the destination IP address.

§transport_protocol: Option<TransportProtocol>

Matchers for the transport layer protocol.

Note that the variants of the TransportProtocol union allow matching on the transport layer protocol itself; to match on specific properties at the transport layer (such as TCP or UDP ports), clients should use the fields of a protocol-specific matcher.

impl PartialEq for Matchers

source§

fn eq(&self, other: &Matchers) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeMarker for Matchers

§

type Owned = Matchers

The owned Rust type which this FIDL type decodes into.
source§

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.
source§

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.
§

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy. Read more
§

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.
