Expand description
Describes where words occur in a line of text.
The simplest approach is say that words are separated by one or
more ASCII spaces (' '
). This works for Western languages
without emojis. A more complex approach is to use the Unicode line
breaking algorithm, which finds break points in non-ASCII text.
The line breaks occur between words, please see the
WordSplitter
trait for
options of how to handle hyphenation of individual words.
Examples
use textwrap::core::Word; use textwrap::word_separators::{WordSeparator, AsciiSpace}; let words = AsciiSpace.find_words("Hello World!").collect::<Vec<_>>(); assert_eq!(words, vec![Word::from("Hello "), Word::from("World!")]);
