Expand description
Create Node
items literally.
Literals and expressions will be transformed to Yaml
automatically by calling Into::into
.
use yaml_peg::node; let k = "a"; assert_eq!(node!(k), node!("a"));
Arrays and maps can be created from this macro directly through brackets ([]
, {}
).
use yaml_peg::{node, yaml_array, yaml_map}; assert_eq!(node!([node!(1), node!(2)]), node!(yaml_array![node!(1), node!(2)])); assert_eq!(node!({node!(1) => node!(2)}), node!(yaml_map![node!(1) => node!(2)]));
The YamlBase::Null
and the YamlBase::Null
are also supported by the syntax:
use yaml_peg::{node, YamlBase}; assert_eq!(node!(YamlBase::Null), node!(null)); assert_eq!(node!(YamlBase::Anchor("x".into())), node!(*"x"));
