Events are asynchronous notifications sent from the server to subscribed clients. Unlike responses, events are not correlated to specific requests.

Variants

NodeStateChanged

A node’s state has changed (e.g., from Running to Recovering). Clients can use this to update UI indicators and monitor pipeline health.

Fields

session_id: String

node_id: String

state: NodeState

timestamp: String

ISO 8601 formatted timestamp

NodeStatsUpdated

A node’s statistics have been updated (packets processed, discarded, errored). These updates are throttled at the source to prevent overload.

Fields

session_id: String

node_id: String

stats: NodeStats

timestamp: String

ISO 8601 formatted timestamp

NodeParamsChanged

A node’s parameters have been updated. Clients can use this to keep their view of the pipeline state in sync.

Fields

session_id: String

node_id: String

params: Value

SessionCreated

Fields

session_id: String

name: Option<String>

created_at: String

ISO 8601 formatted timestamp when the session was created

SessionDestroyed

Fields

session_id: String

NodeAdded

Fields

session_id: String

node_id: String

kind: String

params: Option<Value>

NodeRemoved

Fields

session_id: String

node_id: String

ConnectionAdded

Fields

session_id: String

from_node: String

from_pin: String

to_node: String

to_pin: String

ConnectionRemoved

Fields

session_id: String

from_node: String

from_pin: String

to_node: String

to_pin: String

NodeTelemetry

Telemetry event from a node (transcription results, VAD events, LLM responses, etc.). The data payload contains event-specific fields including event_type for filtering. These events are best-effort and may be dropped under load.

Fields

session_id: String

The session this event belongs to

node_id: String

The node that emitted this event

type_id: String

Packet type identifier (e.g., “core::telemetry/event@1”)

data: Value

Event payload containing event_type, correlation_id, turn_id, and event-specific data

timestamp_us: Option<u64>

Microsecond timestamp from the packet metadata (if available)

timestamp: String

RFC 3339 formatted timestamp for convenience

Trait Implementations

impl Clone for EventPayload

fn clone(&self) -> EventPayload

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventPayload

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EventPayload

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for EventPayload

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TS for EventPayload

type WithoutGenerics = EventPayload

If this type does not have generic parameters, then WithoutGenerics should just be Self. If the type does have generic parameters, then all generic parameters must be replaced with a dummy type, e.g ts_rs::Dummy or (). The only requirement for these dummy types is that EXPORT_TO must be None.

type OptionInnerType = EventPayload

If the implementing type is std::option::Option<T>, then this associated type is set to T. All other implementations of TS should set this type to Self instead.

fn ident() -> String

Identifier of this type, excluding generic parameters.

fn docs() -> Option<String>

JSDoc comment to describe this type in TypeScript - when TS is derived, docs are automatically read from your doc comments or #[doc = ".."] attributes

fn name() -> String

Name of this type in TypeScript, including generic parameters

fn decl_concrete() -> String

Declaration of this type using the supplied generic arguments. The resulting TypeScript definition will not be generic. For that, see TS::decl(). If this type is not generic, then this function is equivalent to TS::decl().

fn decl() -> String

Declaration of this type, e.g. type User = { user_id: number, ... }. This function will panic if the type has no declaration.

fn inline() -> String

Formats this types definition in TypeScript, e.g { user_id: number }. This function will panic if the type cannot be inlined.

fn inline_flattened() -> String

Flatten a type declaration.
This function will panic if the type cannot be flattened.

fn visit_generics(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all type parameters of this type.

fn output_path() -> Option<PathBuf>

Returns the output path to where T should be exported.
The returned path does not include the base directory from TS_RS_EXPORT_DIR.

fn visit_dependencies(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all dependency of this type.

fn dependencies() -> Vec<Dependency>

where Self: 'static,

Resolves all dependencies of this type recursively.

fn export() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem. To export this type together with all of its dependencies, use TS::export_all.

fn export_all() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem, together with all of its dependencies.
To export only this type, without its dependencies, use TS::export.

fn export_all_to(out_dir: impl AsRef<Path>) -> Result<(), ExportError>

where Self: 'static,

Manually export this type into the given directory, together with all of its dependencies.
To export only this type, without its dependencies, use TS::export.

fn export_to_string() -> Result<String, ExportError>

where Self: 'static,

Manually generate bindings for this type, returning a String.
This function does not format the output, even if the format feature is enabled.

fn default_output_path() -> Option<PathBuf>

Returns the output path to where T should be exported.
