struct UserRecord {
    id: Int,
    name: Option<String> = None,
    region: Region = Region::Unknown,
}

enum Region {
    Unknown,
    East,
    West,
}

[
    UserRecord(1, "cympfh", Region::East),
    UserRecord { id = 2, name = "Alan", region = Region::West, },
    UserRecord { id = 3, name = "Bob" },
    UserRecord { id = 4, region = Region::East },
]

Where is `if` statement? `for` loop?

No.

Cumin is not Turing-Complete Programming Language. Just (mini-Programmable) Configuration Language.
