This message defines the standard attribute vocabulary for Google APIs.

An attribute is a piece of metadata that describes an activity on a network service. For example, the size of an HTTP request, or the status code of an HTTP response.

Each attribute has a type and a name, which is logically defined as a proto message field in AttributeContext. The field type becomes the attribute type, and the field path becomes the attribute name. For example, the attribute source.ip maps to field AttributeContext.source.ip.

This message definition is guaranteed not to have any wire breaking change. So you can use it directly for passing attributes across different systems.

NOTE: Different system may generate different subset of attributes. Please verify the system specification before relying on an attribute generated a system.

Fields

origin: Option<Peer>

The origin of a network activity. In a multi hop network activity, the origin represents the sender of the first hop. For the first hop, the source and the origin must have the same content.

source: Option<Peer>

The source of a network activity, such as starting a TCP connection. In a multi hop network activity, the source represents the sender of the last hop.

destination: Option<Peer>

The destination of a network activity, such as accepting a TCP connection. In a multi hop network activity, the destination represents the receiver of the last hop.

request: Option<Request>

Represents a network request, such as an HTTP request.

response: Option<Response>

Represents a network response, such as an HTTP response.

resource: Option<Resource>

Represents a target resource that is involved with a network activity. If multiple resources are involved with an activity, this must be the primary one.

api: Option<Api>

Represents an API operation that is involved to a network activity.

extensions: Vec<Any>

Supports extensions for advanced use cases, such as logs and metrics.

Trait Implementations

impl Clone for AttributeContext

fn clone(&self) -> AttributeContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeContext

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

Formats the value using the given formatter.

impl Default for AttributeContext

fn default() -> Self

Returns the “default value” for a type.

impl Message for AttributeContext

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

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

where B: Buf, Self: Default,

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

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

where B: Buf, Self: Sized,

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

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

where B: Buf, Self: Sized,

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

impl PartialEq for AttributeContext

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