Installation

Using the Umbrella Crate

The fastest way to get started is the neuron umbrella crate with feature flags:

[dependencies]
neuron = { features = ["anthropic"] }

Or install via cargo:

cargo add neuron --features anthropic

Feature Flags

Using Individual Crates

Each neuron crate is independently published. Use them directly for finer control over dependencies:

[dependencies]
neuron-types = "*"
neuron-provider-openai = "*"
neuron-tool = "*"
neuron-loop = "*"

This pulls in only what you need — no transitive dependency on providers you don’t use.

Minimum Supported Rust Version

neuron requires Rust 1.90+ (edition 2024). It uses native async traits (RPITIT) and requires no #[async_trait] macro.

Environment Variables

Each provider loads credentials from environment variables via from_env():
