Struct VsockTaskEnvelope 

pub struct VsockTaskEnvelope {
    pub assignment: Option<TaskAssignment>,
    pub blob_url: String,
    pub tasks_url: String,
    pub otel_endpoint: String,
}

Envelope for dispatching tasks over vsock (or Unix socket) to workers running inside Firecracker microVMs.

The proxy reads TaskAssignment from the orchestrator’s PullTasks stream and wraps it in this envelope with additional environment URLs that the VM worker needs for direct communication with the orchestrator.

Wire format: sequential length-delimited messages on a single connection. Each message is [4-byte big-endian length][protobuf VsockTaskEnvelope]. End-of-stream (connection closed) means no more tasks.

Fields

assignment: Option<TaskAssignment>

The task assignment from the orchestrator.

blob_url: String

Blob API URL for the worker to store/retrieve blobs. e.g., “http://orchestrator:7840/api/v1/blobs"

tasks_url: String

Tasks service URL (for GetOrchestratorForRun discovery). e.g., “http://orchestrator:7837"

otel_endpoint: String

OpenTelemetry collector endpoint for traces, metrics, and logs. e.g., “http://otel-collector:4317"

Trait Implementations

impl Clone for VsockTaskEnvelope

fn clone(&self) -> VsockTaskEnvelope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VsockTaskEnvelope

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

Formats the value using the given formatter.

impl Default for VsockTaskEnvelope

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VsockTaskEnvelope

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for VsockTaskEnvelope

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 VsockTaskEnvelope

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

impl Serialize for VsockTaskEnvelope

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
