Macro unordered_elements_are 

macro_rules! unordered_elements_are {
    ($(,)?) => { ... };
    ($($matcher:expr),* $(,)?) => { ... };
}

Matches a JSON array whose elements, in any order, have a 1:1 correspondence with the provided matchers.

Each element in the input array must match exactly one of the given matchers, and vice versa. Matching fails if the input is not an array, if the number of elements and matchers differ, or if no perfect one-to-one mapping can be found.

Example

This passes:

let value = j!(["a", "b", "c"]);
assert_that!(
    value,
    json::unordered_elements_are![
        j!("c"),
        eq("a"),
        starts_with("b"),
    ]
);

This fails because the element "x" does not match any expected element:

let value = j!(["a", "x", "c"]);
assert_that!(
    value,
    json::unordered_elements_are![
        eq("c"),
        eq("a"),
        eq("b"),
    ]
);

This fails because the input is not an array:

let value = json!("not an array");
assert_that!(
    value,
    json::unordered_elements_are![
        eq("a"),
        eq("b"),
    ]
);

Notes

• Both JSON-aware and native GoogleTest matchers (such as starts_with, contains_substring) can be used directly.
• Wrapping with json::primitive! is no longer needed.
• Direct serde_json::Value inputs (e.g. json!(...)) are supported and compared by structural equality.
