It's an addition to the procedural macros (basically rust compiler plugin)
that generate all the code for binding rust with python.

it adds support for writing:

/// my_fn docs
#[pyfunction]
#[text_signature = "my_fn(a, b, c)"]
/// more docs
fn my_fn(a: i32, b: i32, c: i32) {
    ...
}

instead of:

// docs must start with exactly
// "<signature>\n--\n\n" to be detected as text_signature:

/// my_fn(a, b, c)
/// --
///
/// my_fn docs
/// more docs
#[pyfunction]
fn my_fn(a: i32, b: i32, c: i32) {
    ...
}
