Struct Each

Source
pub struct Each<U, Iterator>
where Iterator: IntoIterator<Item = U>,
{ pub items: Iterator, }
Expand description

A list of items that can be appended into a Document. For each item in items, the callback is invoked, and its return value is appended to the document.

§Example

struct Point(i32, i32);

let items = vec![Point(10, 20), Point(5, 10), Point(6, 42)];

let document = Document::with(Each(
    &items,
    |item, doc| doc.add(Line("Point(".add(item.0).add(",").add(item.1).add(")")))
));

assert_eq!(document.to_string()?, "Point(10,20)\nPoint(5,10)\nPoint(6,42)\n");

And with the tree! macro:

struct Point(i32, i32);

let items = vec![Point(10, 20), Point(5, 10), Point(6, 42)];

let document = tree! {
    <Each items={items} as |item| {
        <Line as {
            "Point(" {item.0} "," {item.1} ")"
        }>
    }>
};

assert_eq!(document.to_string()?, "Point(10,20)\nPoint(5,10)\nPoint(6,42)\n");
