Chapter 13 Iterator code snippet does not compile

[aboudekahil]

Issue

The following code snippet doesn't compile, openIterableDir is not a method of Dir type.

test "iterator looping" {
    var iter = (try std.fs.cwd().openIterableDir(
        ".",
        .{},
    )).iterate();

    var file_count: usize = 0;
    while (try iter.next()) |entry| {
        if (entry.kind == .file) file_count += 1;
    }

    try expect(file_count > 0);
}

Proposed solution

Replace the above snippet with the one suggested below:

test "iterator looping" {
    var iter = (try std.fs.cwd().openDir(".", .{ .iterate = true })).iterate();

    var file_count: usize = 0;
    while (try iter.next()) |entry| {
        if (entry.kind == .file) file_count += 1;
    }

    try expect(file_count > 0);
}
