Struct ProcessingResponse

pub struct ProcessingResponse {
    pub dynamic_metadata: Option<Struct>,
    pub mode_override: Option<ProcessingMode>,
    pub override_message_timeout: Option<Duration>,
    pub response: Option<Response>,
}

For every ProcessingRequest received by the server with the observability_mode field set to false, the server must send back exactly one ProcessingResponse message. [#next-free-field: 11]

Fields

dynamic_metadata: Option<Struct>

Optional metadata that will be emitted as dynamic metadata to be consumed by following filters. This metadata will be placed in the namespace(s) specified by the top-level field name(s) of the struct.

mode_override: Option<ProcessingMode>

Override how parts of the HTTP request and response are processed for the duration of this particular request/response only. Servers may use this to intelligently control how requests are processed based on the headers and other metadata that they see. This field is only applicable when servers responding to the header requests. If it is set in the response to the body or trailer requests, it will be ignored by Envoy. It is also ignored by Envoy when the ext_proc filter config :ref:allow_mode_override <envoy_v3_api_field_extensions.filters.http.ext_proc.v3.ExternalProcessor.allow_mode_override> is set to false.

override_message_timeout: Option<Duration>

When ext_proc server receives a request message, in case it needs more time to process the message, it sends back a ProcessingResponse message with a new timeout value. When Envoy receives this response message, it ignores other fields in the response, just stop the original timer, which has the timeout value specified in :ref:message_timeout <envoy_v3_api_field_extensions.filters.http.ext_proc.v3.ExternalProcessor.message_timeout> and start a new timer with this override_message_timeout value and keep the Envoy ext_proc filter state machine intact. Has to be >= 1ms and <= :ref:max_message_timeout <envoy_v3_api_field_extensions.filters.http.ext_proc.v3.ExternalProcessor.max_message_timeout> Such message can be sent at most once in a particular Envoy ext_proc filter processing state. To enable this API, one has to set max_message_timeout to a number >= 1ms.

response: Option<Response>

Trait Implementations

impl Clone for ProcessingResponse

fn clone(&self) -> ProcessingResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProcessingResponse

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

Formats the value using the given formatter.

impl Default for ProcessingResponse

fn default() -> Self

Returns the “default value” for a type.

impl Message for ProcessingResponse

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 Name for ProcessingResponse

const NAME: &'static str = "ProcessingResponse"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "envoy.service.ext_proc.v3"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for ProcessingResponse

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