Enum yaml_peg::Yaml

pub enum Yaml {
    Null,
    Bool(bool),
    Int(String),
    Float(String),
    Str(String),
    Array(Array),
    Map(Map),
    Anchor(String),
}

YAML data types, but it is recommended to use Node for shorten code.

This type can convert from primitive types by From and Into methods.

use yaml_peg::Yaml;
assert_eq!(Yaml::Int("20".into()), 20.into());
assert_eq!(Yaml::Float("0.001".into()), 1e-3.into());

Also, the iterators can turn into arrays and maps.

use yaml_peg::{Yaml, yaml_array, yaml_map, node};
use std::iter::FromIterator;
let v = vec![node!(1), node!(2), node!(3)];
assert_eq!(Yaml::from_iter(v), yaml_array![node!(1), node!(2), node!(3)]);
let m = vec![(node!(1), node!(2)), (node!(3), node!(4))];
assert_eq!(Yaml::from_iter(m), yaml_map!{node!(1) => node!(2), node!(3) => node!(4)});
