Macro json_path 

macro_rules! json_path {
    () => { ... };
    ( $($piece:expr),+ $(,)? ) => { ... };
}

Creates a JSON path from path pieces, separated by commas

The arguments to this macro represent the path pieces:

• numbers of type u32 are converted to JsonPathPiece::ArrayItem
• strings are converted to JsonPathPiece::ObjectMember

Providing no arguments creates an empty path without any path pieces.

Examples

let json_path = json_path!["outer", 3, "inner"];
assert_eq!(
    json_path,
    [
        ObjectMember("outer".to_owned()),
        ArrayItem(3),
        ObjectMember("inner".to_owned()),
    ]
);
