A typed, identity-bearing realtime transcript event consumed by the session.

Variants

ItemObserved

Observe a provider item and its causal predecessor without committing content yet.

Fields

item_id: String

previous_item_id: Option<String>

role: RealtimeTranscriptRole

response_id: Option<String>

ItemSkipped

Observe a provider item that participates in provider causal ordering but must not materialize transcript content.

Fields

item_id: String

previous_item_id: Option<String>

UserTranscriptFinal

Provider finalized the transcript for a user input item.

Fields

item_id: String

previous_item_id: Option<String>

content_index: u32

text: String

AssistantTextDelta

Provider emitted an assistant display-text delta for an output item — authored text the model writes (e.g. OpenAI realtime response.output_text.delta).

Materializes as crate::types::AssistantBlock::Text.

Fields

response_id: String

delta_id: String

item_id: String

previous_item_id: Option<String>

content_index: u32

delta: String

AssistantTranscriptDelta

Provider emitted an assistant spoken-transcript delta for an output item — text derived from audio output (e.g. OpenAI realtime response.output_audio_transcript.delta).

Identity shape mirrors Self::AssistantTextDelta so the session’s idempotent ordering / staging logic owns dedup uniformly across lanes. Materializes as crate::types::AssistantBlock::Transcript with source: TranscriptSource::Spoken (T9/T10).

Fields

response_id: String

delta_id: String

item_id: String

previous_item_id: Option<String>

content_index: u32

delta: String

AssistantTranscriptTruncated

Provider reported the assistant output item was truncated to the heard transcript prefix.

Fields

response_id: String

item_id: String

content_index: u32

text: String

AssistantTranscriptFinalText

R5-7: provider supplied authoritative final transcript text for an assistant output item, overriding any incomplete delta accumulation.

Necessary for two cases:

1. Final-only providers that emit a single AssistantTranscriptFinal observation without prior deltas.
2. Recovery from delta loss (R5-1: lossy media lane back-pressure may drop transcript deltas; the final’s text is the authoritative reconciliation).

The materializer locates the staged item by (response_id, item_id, content_index), replaces its accumulated content with text, and (if no item is staged yet) creates one on the spoken lane. Flush still happens via AssistantTurnCompleted; this variant only updates the staged content.

Fields

response_id: String

item_id: String

content_index: u32

text: String

AssistantTurnCompleted

Provider turn reached a terminal boundary. The session decides which staged assistant items, if any, are now canonical.

Fields

response_id: String

stop_reason: StopReason

usage: Usage

AssistantTurnInterrupted

Provider turn was interrupted before terminal materialization.

Fields

response_id: String

Trait Implementations

impl Clone for RealtimeTranscriptEvent

fn clone(&self) -> RealtimeTranscriptEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RealtimeTranscriptEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RealtimeTranscriptEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for RealtimeTranscriptEvent

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for RealtimeTranscriptEvent

fn eq(&self, other: &RealtimeTranscriptEvent) -> 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 RealtimeTranscriptEvent

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for RealtimeTranscriptEvent
