Macro test_cell_path 

test_cell_path!() { /* proc-macro */ }

Build a CellPath in Rust using the familiar cell path syntax.

This macro lets you write cell paths the same way you do in Nushell. It also supports inline variables or expressions by wrapping them in a group (parentheses).

Examples

use nu_test_support::test_cell_path;

let simple = test_cell_path!(foo.bar);
assert_eq!(simple.to_string(), "$.foo.bar");

let with_modifiers = test_cell_path!(foo?.bar!);
assert_eq!(with_modifiers.to_string(), "$.foo?.bar!");

let with_literal = test_cell_path!(foo."bar baz".3);
assert_eq!(with_literal.to_string(), r#"$.foo."bar baz".3"#);

let column = "foo";
let index = 3;
let from_vars = test_cell_path!((column).(index));
assert_eq!(from_vars.to_string(), "$.foo.3");
