Rinja

Rinja implements a template rendering engine based on Jinja. It generates Rust code from your templates at compile time based on a user-defined struct to hold the template's context. See below for an example.

All feedback welcome! Feel free to file bugs, requests for documentation and any other feedback to the issue tracker.

Have a look at our Rinja Playground, if you want to try out rinja's code generation online.
