Finja: What If Your Rust Function Was a Jinja Template?

#[finja(
    welcomer => "println!",
    greeting => "Hello, {}",
    name => "guest2"
)]
fn main() {
    let guest1 = "Universe";
    let guest2 = "World";

    {{ welcomer }}("{{ greeting }}", {{ name }});
}

Hi! I made this just for fun - it’s a little experiment that enables Jinja templating (using minijinja) directly on Rust function bodies using an attribute macro.

The code of the function becomes a template that is rendered in the compile time using provided parameters.

There's a slightly more complex example in the repository: https://github.com/synek317/finja

50% of me loves it, 50% thinks it's too much magic.

What do you think?
