Rerun template repository

Template for our private and public repos, containing CI, CoC, etc

When creating a new Rerun repository, use this as a template, then modify it as it makes sense.

This template should be the default for any repository of any kind, including:

• Rust projects
• C++ projects
• Python projects
• Other stuff

This template includes

• License files
• Code of Conduct
• Helpers for checking and linting Rust code
  • cargo-cranky
  • cargo-deny
  • rust-toolchain
• CI for:
  • Spell checking
  • Link checking
  • Rust checks

How to use

Start by clicking "Use this template" at https://github.com/rerun-io/rerun_template/ or follow these instructions.

Then follow these steps:

• Run scripts/template_update.py init --languages cpp,rust,python to delete files you don't need (give the languages you need support for)
• Search and replace all instances of new_repo_name with the name of the repository.
• Search and replace all instances of new_project_name with the name of the project (crate/binary name).
• Search for TODO and fill in all those places
• Replace this README.md with something better
• Commit!

In the future you can always update this repository with the latest changes from the template by running:

• scripts/template_update.py update --languages cpp,rust,python
