Struct google_api_proto::google::cloud::networkservices::v1::extension_chain::Extension

pub struct Extension {
    pub name: String,
    pub authority: String,
    pub service: String,
    pub supported_events: Vec<i32>,
    pub timeout: Option<Duration>,
    pub fail_open: bool,
    pub forward_headers: Vec<String>,
}

A single extension in the chain to execute for the matching request.

Fields

name: String

Required. The name for this extension. The name is logged as part of the HTTP request logs. The name must conform with RFC-1034, is restricted to lower-cased letters, numbers and hyphens, and can have a maximum length of 63 characters. Additionally, the first character must be a letter and the last a letter or a number.

authority: String

Optional. The :authority header in the gRPC request sent from Envoy to the extension service. Required for Callout extensions.

service: String

Required. The reference to the service that runs the extension.

Currently only callout extensions are supported here.

To configure a callout extension, service must be a fully-qualified reference to a backend service in the format: <https://www.googleapis.com/compute/v1/projects/{project}/regions/{region}/backendServices/{backendService}> or <https://www.googleapis.com/compute/v1/projects/{project}/global/backendServices/{backendService}.>

supported_events: Vec<i32>

Optional. A set of events during request or response processing for which this extension is called. This field is required for the LbTrafficExtension resource. It must not be set for the LbRouteExtension resource.

timeout: Option<Duration>

Optional. Specifies the timeout for each individual message on the stream. The timeout must be between 10-1000 milliseconds. Required for Callout extensions.

fail_open: bool

Optional. Determines how the proxy behaves if the call to the extension fails or times out.

When set to TRUE, request or response processing continues without error. Any subsequent extensions in the extension chain are also executed. When set to FALSE or the default setting of FALSE is used, one of the following happens:

• If response headers have not been delivered to the downstream client, a generic 500 error is returned to the client. The error response can be tailored by configuring a custom error response in the load balancer.

• If response headers have been delivered, then the HTTP stream to the downstream client is reset.

forward_headers: Vec<String>

Optional. List of the HTTP headers to forward to the extension (from the client or backend). If omitted, all headers are sent. Each element is a string indicating the header name.

Implementations

impl Extension

pub fn supported_events( &self, ) -> FilterMap<Cloned<Iter<'_, i32>>, fn(_: i32) -> Option<EventType>>

Returns an iterator which yields the valid enum values contained in supported_events.

pub fn push_supported_events(&mut self, value: EventType)

Appends the provided enum value to supported_events.

Trait Implementations

impl Clone for Extension

fn clone(&self) -> Extension

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Extension

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

Formats the value using the given formatter.

impl Default for Extension

fn default() -> Self

Returns the “default value” for a type.

impl Message for Extension

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 Extension

fn eq(&self, other: &Extension) -> 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.
