Struct CompletionRequest 

pub struct CompletionRequest {
    pub model: String,
    pub messages: Vec<ChatMessage>,
    pub tools: Option<Vec<Tool>>,
    pub tool_choice: Option<ToolChoice>,
    pub temperature: f32,
    pub max_tokens: u32,
    pub reasoning_effort: Option<ReasoningEffort>,
    pub provider_attempt_id: Option<String>,
    pub stream: bool,
    pub stream_options: Option<StreamOptions>,
}

A chat-completion request.

Fields

model: String

messages: Vec<ChatMessage>

tools: Option<Vec<Tool>>

tool_choice: Option<ToolChoice>

temperature: f32

max_tokens: u32

reasoning_effort: Option<ReasoningEffort>

provider_attempt_id: Option<String>

Durable runtime identity used for provider idempotency and reconciliation.

stream: bool

OpenAI-compatible streaming flag. Defaults to false and is omitted on the wire in that case.

stream_options: Option<StreamOptions>

OpenAI-compatible streaming options. Providers only include the final usage frame when include_usage is requested explicitly.

Implementations

impl CompletionRequest

pub fn new(model: impl Into<String>, messages: Vec<ChatMessage>) -> Self

New request with the same defaults as the Python wrapper (temperature = 0.3, max_tokens = 4096).

pub fn stream(self, enabled: bool) -> Self

pub fn temperature(self, t: f32) -> Self

pub fn max_tokens(self, n: u32) -> Self

pub fn reasoning_effort(self, effort: ReasoningEffort) -> Self

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

Attach tools. Mirrors the Python default: if a caller adds tools without an explicit choice, we set tool_choice = auto.

pub fn tool_choice(self, choice: ToolChoice) -> Self
