Struct ClaudeCodeProvider 

pub struct ClaudeCodeProvider { /* private fields */ }

Provider that invokes the Claude Code CLI as a subprocess.

Each inference request spawns a fresh claude process. This is the non-interactive approach: the process handles the prompt and exits.

Implementations

impl ClaudeCodeProvider

pub fn new() -> Self

Create a new ClaudeCodeProvider.

The binary path is resolved from CLAUDE_CODE_PATH env var if set, otherwise defaults to "claude" (found via PATH).

Trait Implementations

impl Default for ClaudeCodeProvider

fn default() -> Self

Returns the “default value” for a type.

impl Provider for ClaudeCodeProvider

fn chat_with_system<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, system_prompt: Option<&'life1 str>, message: &'life2 str, model: &'life3 str, temperature: f64, ) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

One-shot chat with optional system prompt.

fn chat_with_history<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, messages: &'life1 [ChatMessage], model: &'life2 str, temperature: f64, ) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Multi-turn conversation. Default implementation extracts the last user message and delegates to chat_with_system.

fn chat<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, request: ChatRequest<'life1>, model: &'life2 str, temperature: f64, ) -> Pin<Box<dyn Future<Output = Result<ChatResponse>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Structured chat API for agent loop callers.

fn capabilities(&self) -> ProviderCapabilities

Query provider capabilities.

fn convert_tools(&self, tools: &[ToolSpec]) -> ToolsPayload

Convert tool specifications to provider-native format.

fn simple_chat<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, message: &'life1 str, model: &'life2 str, temperature: f64, ) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Simple one-shot chat (single user message, no explicit system prompt).

fn supports_native_tools(&self) -> bool

Whether provider supports native tool calls over API.

fn supports_vision(&self) -> bool

Whether provider supports multimodal vision input.

fn warmup<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Warm up the HTTP connection pool (TLS handshake, DNS, HTTP/2 setup). Default implementation is a no-op; providers with HTTP clients should override.

fn chat_with_tools<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, messages: &'life1 [ChatMessage], _tools: &'life2 [Value], model: &'life3 str, temperature: f64, ) -> Pin<Box<dyn Future<Output = Result<ChatResponse>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Chat with tool definitions for native function calling support. The default implementation falls back to chat_with_history and returns an empty tool_calls vector (prompt-based tool use only).

fn supports_streaming(&self) -> bool

Whether provider supports streaming responses. Default implementation returns false.

fn supports_streaming_tool_events(&self) -> bool

Whether provider can emit structured tool-call stream events.

fn stream_chat_with_system( &self, _system_prompt: Option<&str>, _message: &str, _model: &str, _temperature: f64, _options: StreamOptions, ) -> BoxStream<'static, StreamResult<StreamChunk>>

Streaming chat with optional system prompt. Returns an async stream of text chunks. Default implementation falls back to non-streaming chat.

fn stream_chat_with_history( &self, messages: &[ChatMessage], model: &str, temperature: f64, options: StreamOptions, ) -> BoxStream<'static, StreamResult<StreamChunk>>

Streaming chat with history. Default implementation extracts the last user message and delegates to stream_chat_with_system, mirroring the non-streaming chat_with_history.

fn stream_chat( &self, request: ChatRequest<'_>, model: &str, temperature: f64, options: StreamOptions, ) -> BoxStream<'static, StreamResult<StreamEvent>>

Structured streaming chat interface.
