Function yaml_peg::dumper::dump

pub fn dump<I>(nodes: I) -> String where
    I: IntoIterator,
    I::Item: Dumper, 

Dump the YAML data in to block format.

Dumper will use plain string when the string is none-wrapped, otherwise it use literal string and trim the last white spaces.

use yaml_peg::{dump, node, dumper::NL};

let doc = dump(vec![
    node!({
        node!("a") => node!("b"),
        node!("c") => node!("d"),
    }),
]);
assert_eq!(doc, format!("a: b{0}c: d{0}", NL));

When calling parse function then dump the string, the string can be reformatted.
