Hello
I am trying to use Rust-code in Askama... Take for example this:
{% if restaurant.opening_hours.as_ref().unwrap().iter().find(|x| x.is_day(day.to_string())) %}
This gives the following parsing error:
error: problems parsing template source at row 139, column 92 near:
"(|x| x.is_day(day.to_string())) %}\n "...
I think this is because of the |
-character. Is there a way to escape this in Askama?
I'm not familiar with Askama but it looks like closures aren't supported (yet).
This is going even further out on a limb (since I have no idea what is possible), but for this particular case maybe you could build an iterator of (xs, copies_of_day)
and have a function
fn is_xs_day(tuple: (&Whatever, &DaysType)) -> bool {
tuple.0.is_day(tuple.1.to_string())
}
And then put that in the find
:
{% if restaurant
.opening_hours
.as_ref()
.unwrap()
.iter()
.zip(std::iter::repeat(day))
.find(is_xs_day)
%}
