Enum Overflow 

#[non_exhaustive]
pub enum Overflow {
    KeepWords,
    Fold,
    Ellipsis,
}

What happens to a line wider than the width it is given.

Each variant is a policy a layout offers a column or a paragraph. No policy splits a grapheme cluster.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

KeepWords

Break lines at spaces only. A word wider than the width keeps a line of its own and runs past the width.

Fold

Break lines at spaces, and break a word wider than the width between clusters. A cluster wider than the width keeps a line of its own.

Ellipsis

Keep one line and cut it with an ELLIPSIS when it is too wide.
