Enum WellKnownTypes 

pub enum WellKnownTypes {
    Listener,
    HttpConnectionManager,
    RouteConfiguration,
    ScopedRouteConfiguration,
    VirtualHost,
    Cluster,
    ClusterLoadAssignment,
    Secret,
    Runtime,
}

Well known types that Any messages may contain while dealing with XDS DiscoveryRequests and DiscoveryResponses.

This type currently suppors the top-level types for xDS services and the HttpConnectionManager type that most applications will need to work with while managing a Listener. It doesn’t include support for extension types or typed configs.

match WellKnownTypes::from_type_url(&any.type_url) {
    Some(WellKnownTypes::Listener) => {
        do_something_with_listener(Listener::decode(&any.value).unwrap())
    }
    _ => todo!(),
}

pbjson

With the pbjson feature enabled, Any messages use WellKnownTypes for canonical json conversion and any type listed in WellKnownTypes will be serialized as a struct instead of as an opaque blob. For example, an Any containing an HttpConnectionManager would serialize to.

{
    "@type": "type.googleapis.com/envoy.extensions.filters.network.http_connection_manager.v3.HttpConnectionManager",
    "route_config": {
        "name": "test_route"
    }
}

Variants

VirtualHost

A VirtualHost, used in VHDS.

Cluster

A Cluster, used in CDS

ClusterLoadAssignment

A ClusterLoadAssignment, used in EDS.

Secret

A Secret, used in SDS.

Runtime

A Runtime, used in RTDS.

Implementations

impl WellKnownTypes

pub fn all() -> &'static [WellKnownTypes]

pub fn from_type_url(type_url: &str) -> Option<Self>

pub fn type_url(&self) -> &'static str

Trait Implementations

impl Clone for WellKnownTypes

fn clone(&self) -> WellKnownTypes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for WellKnownTypes

impl Debug for WellKnownTypes

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

Formats the value using the given formatter.

impl Enum for WellKnownTypes

const LENGTH: usize

Length of the enum.

fn from_usize(value: usize) -> Self

Takes an usize, and returns an element matching into_usize function.

fn into_usize(self) -> usize

Returns an unique identifier for a value within range of 0..Array::LENGTH.

impl<V> EnumArray<V> for WellKnownTypes

type Array = [V; 9]

Representation of an enum map for type V.

impl Eq for WellKnownTypes

impl PartialEq for WellKnownTypes

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

Tests for self and other values to be equal, and is used by ==.

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

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