Struct google_api_proto::google::cloud::networkservices::v1beta1::endpoint_matcher::MetadataLabelMatcher

pub struct MetadataLabelMatcher {
    pub metadata_label_match_criteria: i32,
    pub metadata_labels: Vec<MetadataLabels>,
}

The matcher that is based on node metadata presented by xDS clients.

Fields

metadata_label_match_criteria: i32

Specifies how matching should be done.

Supported values are: MATCH_ANY: At least one of the Labels specified in the matcher should match the metadata presented by xDS client. MATCH_ALL: The metadata presented by the xDS client should contain all of the labels specified here.

The selection is determined based on the best match. For example, suppose there are three EndpointPolicy resources P1, P2 and P3 and if P1 has a the matcher as MATCH_ANY <A:1, B:1>, P2 has MATCH_ALL <A:1,B:1>, and P3 has MATCH_ALL <A:1,B:1,C:1>.

If a client with label <A:1> connects, the config from P1 will be selected.

If a client with label <A:1,B:1> connects, the config from P2 will be selected.

If a client with label <A:1,B:1,C:1> connects, the config from P3 will be selected.

If there is more than one best match, (for example, if a config P4 with selector <A:1,D:1> exists and if a client with label <A:1,B:1,D:1> connects), an error will be thrown.

metadata_labels: Vec<MetadataLabels>

The list of label value pairs that must match labels in the provided metadata based on filterMatchCriteria This list can have at most 64 entries. The list can be empty if the match criteria is MATCH_ANY, to specify a wildcard match (i.e this matches any client).

Implementations

impl MetadataLabelMatcher

pub fn metadata_label_match_criteria(&self) -> MetadataLabelMatchCriteria

Returns the enum value of metadata_label_match_criteria, or the default if the field is set to an invalid enum value.

pub fn set_metadata_label_match_criteria( &mut self, value: MetadataLabelMatchCriteria, )

Sets metadata_label_match_criteria to the provided enum value.

Trait Implementations

impl Clone for MetadataLabelMatcher

fn clone(&self) -> MetadataLabelMatcher

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataLabelMatcher

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

Formats the value using the given formatter.

impl Default for MetadataLabelMatcher

fn default() -> Self

Returns the “default value” for a type.

impl Message for MetadataLabelMatcher

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for MetadataLabelMatcher

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

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

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.
