Struct DeepseekAgent 

pub struct DeepseekAgent { /* private fields */ }

An agent that combines a Conversation with a set of callable tools.

Build one with the fluent builder methods, then call chat to start a turn:

use ds_api::{DeepseekAgent, tool};
use serde_json::{Value, json};

struct MyTool;

#[tool]
impl ds_api::Tool for MyTool {
    async fn greet(&self, name: String) -> Value {
        json!({ "greeting": format!("Hello, {name}!") })
    }
}

let agent = DeepseekAgent::new("sk-...")
    .add_tool(MyTool);

Implementations

impl DeepseekAgent

pub fn new(token: impl Into<String>) -> Self

Create a new agent with the given API token.

pub fn add_tool<TT: Tool + 'static>(self, tool: TT) -> Self

Register a tool (builder-style, supports chaining).

The tool’s protocol-level function names are indexed so incoming tool-call requests from the model can be dispatched to the correct implementation.

pub fn chat(self, user_message: &str) -> AgentStream

Push a user message and return an AgentStream that drives the full agent loop (API calls + tool execution).

pub fn with_streaming(self) -> Self

Enable SSE streaming for each API turn (builder-style).

pub fn with_system_prompt(self, prompt: impl Into<String>) -> Self

Prepend a permanent system prompt to the conversation history (builder-style).

System messages added this way are never removed by the built-in summarizers.

pub fn with_summarizer(self, summarizer: impl Summarizer + 'static) -> Self

Replace the summarizer used for context-window management (builder-style).
