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

32// Tolerant JSON repair — sinks the LLM-JSON repair pipeline from lc-core so
33// that `ToolCall::parse_arguments` (in this crate) shares a single tolerant
34// parser with lc-core's `json_parse` instead of duplicating strict parsing.
