2//! Shared types for the langchainrust workspace.
3//!
4//! This crate contains types that are needed by multiple sub-crates,
5//! breaking circular dependencies:
6//!
7//! - **Tool types** (`ToolCall`, `FunctionCall`, `ToolCallResult`): needed by
8//! both `lc-schema` (Message uses ToolCall) and `lc-core` (tool definitions).
9//!
10//! - **Document types** (`Document`, `VectorDocument`, `SearchResult`, `ChunkDocument`):
11//! needed by both `lc-vector-stores` and `lc-rag`.
12//!
13//! - **Splitter types** (`TextSplitter`, `RecursiveCharacterSplitter`):
14//! needed by both `lc-vector-stores` and `lc-rag`.
