Macro elements_are 

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

Matches a JSON array with elements that satisfy the given matchers, in order.

Each element of the JSON array is matched against a corresponding Matcher. The array must have the same length as the list of matchers, and all matchers must succeed.

This macro supports two forms:

• Bracketed: elements_are!([matcher1, matcher2, ...])
• Unbracketed: elements_are!(matcher1, matcher2, ...)

Callers should prefer the public-facing json::elements_are! macro.

Examples

Basic usage:

let value = j!(["alex", "bart", "cucumberbatch"]);
assert_that!(
    value,
    json::elements_are![
        j!("alex"),
        starts_with("b"),
        char_count(eq(13))
    ]
);

Nested example:

let value = j!([["x", "y"], ["z"]]);
assert_that!(
    value,
    json::elements_are![
        json::elements_are![j!("x"), eq("y")],
        json::elements_are![eq("z")]
    ]
);

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.
