Function join_with_commas 

pub fn join_with_commas(layouts: Vec<Box<Layout>>) -> Box<Layout>

Joins a collection of layouts with comma separators.

This convenience function takes a vector of layouts and combines them with comma-space separators (“, “) between each element. It’s equivalent to join_with(layouts, comma()) but note that the underlying implementation adds both comma and space. This is the standard way to create comma-separated lists like function parameters, array elements, or object properties.

Parameters

• layouts - Vector of layouts to join with commas

Returns

A single layout with all input layouts separated by “, “, or null if empty.

Examples

use typeset::*;

// Function parameter list
let params = join_with_commas(vec![
    text_str("x: i32"),
    text_str("y: i32"),
    text_str("z: String")
]);

let function = comp(
    text_str("fn example("),
    comp(params, text_str(")"), false, false),
    false, false
);

// Output: "fn example(x: i32, y: i32, z: String)"

use typeset::*;

// Array elements that may break
let array = brackets(
    grp(join_with_commas(vec![
        text_str("element1"),
        text_str("element2"),
        text_str("element3")
    ]))
);

// Fits: "[element1, element2, element3]"
// Breaks: "[element1,
//          element2,
//          element3]"

use typeset::*;

// JSON-like object properties
let object = braces(
    nest(join_with_commas(vec![
        comp(text_str("\"name\""), text_str(": \"John\""), true, false),
        comp(text_str("\"age\""), text_str(": 30"), true, false)
    ]))
);
