Enum MessagePhase 

pub enum MessagePhase {
    Commentary,
    FinalAnswer,
}

Phase label for assistant messages in the Responses API.

For gpt-5.3-codex+ multi-turn conversations, preserving and resending the original phase value avoids quality / latency degradation — the model relies on it to disambiguate commentary-style reasoning from the final answer. Opaque to SMG otherwise; preserved verbatim through store+retrieve, SSE output, and upstream passthrough.

fn clone(&self) -> MessagePhase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MessagePhase

impl Debug for MessagePhase

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessagePhase

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for MessagePhase

impl JsonSchema for MessagePhase

fn schema_name() -> String

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 is_referenceable() -> bool

impl PartialEq for MessagePhase

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
