Overview

candid-gen is a CLI tool that automates the generation of Candid interface files from Rust canisters for Internet Computer (IC) projects. It simplifies the process of creating .did files, ensuring that your Rust canisters are properly documented and ready for deployment on the IC.

Features

• Automatically generates Candid interface files from Rust canisters.
• Supports specifying individual canisters or generating files for all canisters in a project.
• Ensures that all necessary tools and targets are installed and available.
