Struct ResponsesRequestBuilder 

pub struct ResponsesRequestBuilder { /* private fields */ }

Builder for ResponsesRequest.

Implementations

impl ResponsesRequestBuilder

pub fn client<VALUE: Into<DeepSeekClient>>(self, value: VALUE) -> Self

pub fn model<VALUE: Into<String>>(self, value: VALUE) -> Self

ID of the model to use. The Responses API currently only supports deepseek-v4-flash.

pub fn input<VALUE: Into<Input>>(self, value: VALUE) -> Self

The input to the model. Either a plain string (treated as a single user message), or a list of input items.

At least one of input and instructions is required.

pub fn instructions<VALUE: Into<String>>(self, value: VALUE) -> Self

A system-level instruction, inserted as the first system message of the model’s context.

pub fn reasoning<VALUE: Into<Reasoning>>(self, value: VALUE) -> Self

Configuration of the thinking mode.

pub fn max_output_tokens<VALUE: Into<u32>>(self, value: VALUE) -> Self

An upper bound for the number of tokens that can be generated in the response, including both the visible output tokens and the reasoning tokens.

pub fn stream<VALUE: Into<bool>>(self, value: VALUE) -> Self

If set to true, the response is streamed as semantic server-sent events. The final event is response.completed / response.incomplete / response.failed (there is no data: [DONE] message).

pub fn temperature<VALUE: Into<f64>>(self, value: VALUE) -> Self

Possible values: <= 2

Default value: 1

What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. Has no effect in thinking mode.

pub fn top_p<VALUE: Into<f64>>(self, value: VALUE) -> Self

Possible values: <= 1

Default value: 1

An alternative to sampling with temperature, called nucleus sampling. Has no effect in thinking mode.

pub fn text<VALUE: Into<Text>>(self, value: VALUE) -> Self

Configuration of the text output.

pub fn tools<VALUE: Into<Vec<Tool>>>(self, value: VALUE) -> Self

A list of tools the model may call. Function names must be non-empty, at most 128 characters, match ^[a-zA-Z0-9_-]+$, and be unique across all tools. Besides function, the built-in web_search tool is supported and executed on the server side.

pub fn tool<VALUE, FROM_VALUE: Into<VALUE>>(self, item: FROM_VALUE) -> Self

where Vec<Tool>: Default + Extend<VALUE>,

A list of tools the model may call. Function names must be non-empty, at most 128 characters, match ^[a-zA-Z0-9_-]+$, and be unique across all tools. Besides function, the built-in web_search tool is supported and executed on the server side.

pub fn tool_choice<VALUE: Into<ToolChoice>>(self, value: VALUE) -> Self

Controls which (if any) tool is called by the model.

none means the model will not call any tool and instead generates a message. auto (default) means the model can pick between generating a message or calling one or more tools. required means the model must call one or more tools.

Specifying a particular tool via {"type": "function", "name": "my_function"} forces the model to call that tool.

pub fn top_logprobs<VALUE: Into<u32>>(self, value: VALUE) -> Self

Possible values: <= 20

An integer between 0 and 20 specifying the number of most likely tokens to return at each token position, each with an associated log probability.

pub fn user<VALUE: Into<String>>(self, value: VALUE) -> Self

A custom end-user identifier, with allowed character set [a-zA-Z0-9\-_] and a maximum length of 512. Do not include user privacy information.

pub fn build(self) -> Result<ResponsesRequest, ResponsesRequestBuilderError>

Builds a new ResponsesRequest.

Errors

If a required field has not been initialized.

Trait Implementations

impl Default for ResponsesRequestBuilder

fn default() -> Self

Returns the “default value” for a type.
