Setup Development Environment

Follow the steps below to get CocoIndex built on the latest codebase locally - if you are making changes to CocoIndex functionality and want to test it out.

🦀 Install Rust

If you don't have Rust installed, run
```
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
```
Already have Rust? Make sure it's up to date
```
rustup update
```
Setup Python virtual environment:
```
python3 -m venv .venv
```
Activate the virtual environment, before any installing / building / running:
```
. .venv/bin/activate
```
Install required tools:
```
pip install maturin
```
Build the library. Run at the root of cocoindex directory:
```
maturin develop -E all,dev
```
Install and enable pre-commit hooks. This ensures all checks run automatically before each commit:
```
pre-commit install
```
Before running a specific example, set extra environment variables, for exposing extra traces, allowing dev UI, etc.
```
. ./.env.lib_debug
```
