impl Render for borrows ?

[RCasatta]

I struggled a bit understanding why this code doesn't work

#[test]
fn yet_another_test() {
    let mut vec = vec![];
    let a = html! { div { "foo" } };
    vec.push(a);
    let b = html! { div { "bar" } };
    vec.push(b);
    dbg!(&vec);

    let f = html! { @for el in &vec { (el) } };
    assert_eq!("<div>foo</div><div>bar</div>", f.into_string());
}

before realizing I had to Dereference el -> *el

Maybe it's possible to impl Render for borrowed values ?

That's a good point.

I think it would be possible to add an impl for &PreEscaped<T>.

But I don't think we can generalize beyond that. An impl for all &T will conflict with the existing blanket impl for T: Display, because Display is implemented for all &T already.

I think the ideal solution is to remove the blanket impl for T: Display. This is what markup.rs and sailfish do. But we'll need to check how much code that breaks.

I think it would be possible to add an impl for &PreEscaped.

this would be nice since it will cover most common case I think

This is fixed by #320
