Struct Completion 

pub struct Completion {
    pub content: String,
    pub tool_calls: Vec<ToolCall>,
    pub finish_reason: Option<String>,
    pub usage: Option<TokenUsage>,
    pub reasoning_content: Option<String>,
}

One step of model output.

Fields

content: String

tool_calls: Vec<ToolCall>

finish_reason: Option<String>

usage: Option<TokenUsage>

reasoning_content: Option<String>

DeepSeek reasoning/thinking content. Stored in the transcript and echoed back on subsequent requests to satisfy the API contract.

Implementations

impl Completion

pub fn extract_inline_reasoning(&mut self)

Normalise chain-of-thought that a model emitted inline in the content field wrapped in <think>…</think> tags into the dedicated Completion::reasoning_content channel.

Many DeepSeek-R1 style deployments (and OpenAI-compatible proxies) don’t populate the separate reasoning_content SSE field; they stream the thinking inline as <think>…</think> inside content. Downstream the TUI markdown renderer parses those tags as an HTML block and silently drops the whole section — so the thinking is visible while streaming but disappears once the turn finalises and the assistant block is re-rendered from content.

This moves the inner text into reasoning_content (so the existing AgentEvent::Reasoning → thinking-block pipeline lights up) and strips the tags from content (so the answer renders cleanly).

No-op when reasoning_content is already populated (true reasoner models that use the dedicated field) or when no <think> tag is present.
