Macro yaml_peg::node

macro_rules! node {
    ([$($token : tt) *]) => { ... };
    ({ $($token : tt) * }) => { ... };
    (* $anchor : expr) => { ... };
    ($yaml : expr) => { ... };
}

Create Node items literally.

Literals and expressions will be transformed to Yaml automatically by calling Into::into.

use yaml_peg::{node, Node};

let k = "a";
assert_eq!(node!(k), node!("a"));
assert_eq!(node!(()), Node::from(()));

Arrays and maps can be created from this macro directly through brackets ([], {}).

use yaml_peg::{node, yaml_array, yaml_map};

assert_eq!(node!([1, 2]), node!(yaml_array![1, 2]));
assert_eq!(node!({1 => 2}), node!(yaml_map! { 1 => 2 }));

The YamlBase::Anchor is also supported by the syntax:

use yaml_peg::{node, YamlBase};

assert_eq!(node!(YamlBase::Anchor("x".into())), node!(*"x"));

For ArcNode, please use node_arc!, which has same API.
