Fields

created_at: u64

Unix timestamp (in seconds) when this Response was created.

error: Option<ErrorObject>

Error object if the API failed to generate a response.

id: String

Unique identifier for this response.

incomplete_details: Option<IncompleteDetails>

Details about why the response is incomplete, if any.

instructions: Option<String>

Instructions that were inserted as the first item in context.

max_output_tokens: Option<u32>

The value of max_output_tokens that was honored.

metadata: Option<HashMap<String, String>>

Metadata tags/values that were attached to this response.

model: String

Model ID used to generate the response.

object: String

The object type – always response.

output: Vec<OutputContent>

The array of content items generated by the model.

output_text: Option<String>

SDK-only convenience property that contains the aggregated text output from all output_text items in the output array, if any are present. Supported in the Python and JavaScript SDKs.

usage: Option<Usage>

Token usage statistics for this request.

user: Option<String>

End-user ID for which this response was generated.

Trait Implementations

impl Clone for Response

fn clone(&self) -> Response

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Response

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Response

fn deserialize<__D>( __deserializer: __D, ) -> Result<Response, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Response

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
