Variants

ControlMessage

A control-stream message was sent or received (event type 0).

Fields

direction: Direction

Send or receive.

message_type: u64

Wire message type ID (e.g. 0x03 for SUBSCRIBE).

message: Value

Decoded message fields as an opaque CBOR value.

raw: Option<Vec<u8>>

Raw wire bytes (only at full detail level).

StreamOpened

A QUIC stream was opened (event type 1).

Fields

stream_id: u64

QUIC stream ID.

direction: Direction

Outgoing or incoming.

stream_type: StreamType

Stream type.

StreamClosed

A QUIC stream was closed (event type 2).

Fields

stream_id: u64

QUIC stream ID.

error_code: u64

Error code (0 = clean close).

ObjectHeader

An object header was parsed from a data stream (event type 3).

Fields

stream_id: u64

Stream ID this object arrived on.

group: u64

Group ID.

object: u64

Object ID.

publisher_priority: u64

Publisher priority.

object_status: u64

Object status (0=normal, 1=end-of-group, etc.).

ObjectPayload

Object payload bytes were received or sent (event type 4).

Fields

stream_id: u64

Stream ID.

group: u64

Group ID.

object: u64

Object ID.

size: u64

Payload size in bytes.

payload: Option<Vec<u8>>

Payload bytes (only at headers+data or full level).

StateChange

Session FSM phase transition (event type 5).

Fields

from: String

Previous session phase.

to: String

New session phase.

Error

Protocol or transport error (event type 6).

Fields

error_code: u64

Error code.

reason: String

Human-readable reason.

Annotation

User-defined annotation (event type 7).

Fields

label: String

User-defined label.

data: Value

User-defined data (any CBOR type).

Trait Implementations

impl Clone for EventData

fn clone(&self) -> EventData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventData

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

Formats the value using the given formatter.

impl PartialEq for EventData

fn eq(&self, other: &EventData) -> 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 StructuralPartialEq for EventData
