rust-langgraph 0.1.0

Stateful graph runtime for LLM workflows in Rust (community project; not affiliated with LangChain). Pregel-style execution: nodes, conditional edges, checkpoints, streaming. Optional adapters for Ollama, OpenAI, OpenRouter (OpenAI-compatible), and Anthropic; optional ReAct agent + tools. Crate import: rust_langgraph (underscore). Default features include in-memory checkpoints. Enable Cargo features explicitly for LLM modules (e.g. ollama, openai, openrouter, anthropic, prebuilt). See README.md on crates.io for copy-paste Cargo.toml, env vars, and common mistakes.

# THIS FILE IS AUTOMATICALLY GENERATED BY CARGO
#
# When uploading crates to the registry Cargo will automatically
# "normalize" Cargo.toml files for maximal compatibility
# with all versions of Cargo and also rewrite `path` dependencies
# to registry (e.g., crates.io) dependencies.
#
# If you are reading this file be aware that the original Cargo.toml
# will likely look very different (and much more reasonable).
# See Cargo.toml.orig for the original contents.
