## Contributing to Lettre
The following guidelines are inspired from the [hyper project](https://github.com/hyperium/hyper/blob/master/CONTRIBUTING.md).
### Code formatting
All code must be formatted using `rustfmt`.
### Commit Message Format
Each commit message consists of a header, a body and a footer. The header has a special format that includes a type, a scope and a subject:
```text
<type>(<scope>): <subject> <BLANK LINE> <body> <BLANK LINE> <footer>
```
Any line of the commit message cannot be longer 72 characters.
**type** must be one of the following:
feat: A new feature
fix: A bug fix
docs: Documentation only changes
style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
refactor: A code change that neither fixes a bug or adds a feature
perf: A code change that improves performance
test: Adding missing tests
chore: Changes to the build process or auxiliary tools and libraries such as documentation generation
**scope** is the lettre part that is being touched. Examples:
email
transport-smtp
transport-file
transport
all
The body explains the change, and the footer contains relevant changelog notes and references to fixed issues.
