Struct epaint::text::text_layout::RowBreakCandidates

struct RowBreakCandidates {
    space: Option<usize>,
    cjk: Option<usize>,
    pre_cjk: Option<usize>,
    dash: Option<usize>,
    punctuation: Option<usize>,
    any: Option<usize>,
}

Keeps track of good places to break a long row of text. Will focus primarily on spaces, secondarily on things like -

Fields

space: Option<usize>

Breaking at or other whitespace is always the primary candidate.

cjk: Option<usize>

Logograms (single character representing a whole word) or kana (Japanese hiragana and katakana) are good candidates for line break.

pre_cjk: Option<usize>

Breaking anywhere before a CJK character is acceptable too.

dash: Option<usize>

Breaking at a dash is a super- good idea.

punctuation: Option<usize>

This is nicer for things like URLs, e.g. www. example.com.

any: Option<usize>

Breaking after just random character is some times necessary.
