Struct ProcessingRequest

pub struct ProcessingRequest {
    pub metadata_context: Option<Metadata>,
    pub attributes: HashMap<String, Struct>,
    pub observability_mode: bool,
    pub request: Option<Request>,
}

This represents the different types of messages that Envoy can send to an external processing server. [#next-free-field: 11]

Fields

metadata_context: Option<Metadata>

Dynamic metadata associated with the request.

attributes: HashMap<String, Struct>

The values of properties selected by the request_attributes or response_attributes list in the configuration. Each entry in the list is populated from the standard :ref:attributes <arch_overview_attributes> supported across Envoy.

observability_mode: bool

Specify whether the filter that sent this request is running in :ref:observability_mode <envoy_v3_api_field_extensions.filters.http.ext_proc.v3.ExternalProcessor.observability_mode> and defaults to false.

• A value of false indicates that the server must respond to this message by either sending back a matching ProcessingResponse message, or by closing the stream.
• A value of true indicates that the server should not respond to this message, as any responses will be ignored. However, it may still close the stream to indicate that no more messages are needed.

request: Option<Request>

Each request message will include one of the following sub-messages. Which ones are set for a particular HTTP request/response depend on the processing mode.

Trait Implementations

impl Clone for ProcessingRequest

fn clone(&self) -> ProcessingRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProcessingRequest

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

Formats the value using the given formatter.

impl Default for ProcessingRequest

fn default() -> Self

Returns the “default value” for a type.

impl Message for ProcessingRequest

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 ProcessingRequest

const NAME: &'static str = "ProcessingRequest"

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 ProcessingRequest

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