Struct google_api_proto::google::cloud::visionai::v1::PacketHeader

pub struct PacketHeader {
    pub capture_time: Option<Timestamp>,

The message that represents packet header.

Fields

capture_time: Option<Timestamp>

Input only. The capture time of the packet.

type: Option<PacketType>

Input only. Immutable. The type of the payload.

metadata: Option<Struct>

Input only. This field is for users to attach user managed metadata.

server_metadata: Option<ServerMetadata>

Output only. Metadata that the server appends to each packet before sending it to receivers. You don’t need to set a value for this field when sending packets.

series_metadata: Option<SeriesMetadata>

Input only. Immutable. Metadata that the server needs to know where to write the packets to. It’s only required for the first packet.

flags: i32

Immutable. Packet flag set. SDK will set the flag automatically.

trace_context: String

Immutable. Header string for tracing across services. It should be set when the packet is first arrived in the stream server.

The input format is a lowercase hex string:

• version_id: 1 byte, currently must be zero - hex encoded (2 characters)
• trace_id: 16 bytes (opaque blob) - hex encoded (32 characters)
• span_id: 8 bytes (opaque blob) - hex encoded (16 characters)
• trace_options: 1 byte (LSB means tracing enabled) - hex encoded (2 characters) Example: “00-404142434445464748494a4b4c4d4e4f-6162636465666768-01” v trace_id span_id options

Trait Implementations

impl Clone for PacketHeader

fn clone(&self) -> PacketHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PacketHeader

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

Formats the value using the given formatter.

impl Default for PacketHeader

fn default() -> Self

Returns the “default value” for a type.

impl Message for PacketHeader

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 PacketHeader

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