Enum TextWrap 

#[non_exhaustive]
pub enum TextWrap {
    Shift,
    Hard,
    Word(u16),
}

Text breaking.

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.

Shift

Don’t break, shift text to the left.

Hard

Hard break at the right border.

Word(u16)

Wraps the text at word boundaries.

The parameter sets a right margin area. If a space is encountered in this area a line-break is inserted. If the last word is starts before this margin it will be broken at a hyphen, soft-hyphen, a zero-width space or the space before the start. If this fails a hard break is inserted.

A value of 8 gives a good overall layout for most text. There will be no lines with very short words clinging to a line, that stand out excessively.
