Struct StreamRequest 

pub struct StreamRequest {
    pub system_prompt: String,
    pub messages: Vec<AgentMessage>,
    pub tools: Vec<ToolSchema>,
    pub temperature: Option<f32>,
    pub max_output_tokens: Option<u32>,
    pub reasoning: ReasoningEffort,
    pub provider_extras: Value,
    pub force_tool_call: bool,
}

Inputs for one LLM call.

Fields

system_prompt: String

System prompt prepended by the provider.

messages: Vec<AgentMessage>

Conversation transcript. The transport converts to provider-native format before sending.

tools: Vec<ToolSchema>

Tool schemas the provider should expose to the model.

temperature: Option<f32>

Optional sampling controls. Implementations may ignore.

max_output_tokens: Option<u32>

reasoning: ReasoningEffort

Reasoning-effort knob shipped to the provider. Typed contract; each StreamFn impl owns the wire mapping (OpenRouter’s reasoning: {effort} block, Fireworks’ top-level reasoning_effort, etc.). Single source of truth — replaces the stringly-typed provider_config["reasoning_effort"] knob and the hardcoded per-bridge defaults.

provider_extras: Value

Provider-specific extras (e.g., response format, custom routing pins). Open-by-design leaf — typed at the leaf is overkill given provider fragmentation. Reasoning effort is NOT carried here; use the typed reasoning field above.

force_tool_call: bool

When true, the wire request sets tool_choice: "required" — the provider MUST emit a tool call (no plain-text or empty completion). Coercive narrowing for the framing turn: paired with OpeningGate’s compact catalog, this forces the model to pick a message or planning tool instead of emitting reasoning-only text and skipping the structured turn. Default false leaves tool choice to the provider for every other turn.

Trait Implementations
