Struct language_reporting::Document

pub struct Document { /* fields omitted */ }

The Document is the root node in a render tree.

The tree! macro produces a Document, and you can also build one manually.

use render_tree::prelude::*;
use render_tree::Render;

fn main() -> std::io::Result<()> {
    let document = Document::empty()
        // You can add a `Line` to a document, with nested content
        .add(Line(
            // Strings implement `Render`
            "Hello"
        ))
        .add(Line(
            1.add(".").add(10)
        ))
        .add(Section("code", |doc|
            doc.add("[E").add(1000).add("]")
        ));

    assert_eq!(document.to_string()?, "Hello\n1.10\n[E1000]");

    Ok(())
}

The above example is equivalent to this use of the tree! macro:

#[macro_use]
extern crate render_tree;
use render_tree::prelude::*;

fn main() -> std::io::Result<()> {
    let document = tree! {
        <Line as { "Hello" }>
        <Line as {
            {1} "." {10}
        }>
        <Section name="code" as {
            "[E" {1000} "]"
        }>
    };

    assert_eq!(document.to_string()?, "Hello\n1.10\n[E1000]");

    Ok(())
}
