textwrap

Uses look-ahead to minimize gaps at line ends for balanced text, as demonstrated with the 'smawk' feature enabling smarter line breaks compared to basic wrapping.

Offers customizable wrap algorithms and word splitters via the Options struct, and allows enabling only necessary features to keep binaries lean, as highlighted in the Cargo features documentation.

Handles Unicode strings by default and supports hyphenation for about 70 languages using high-quality TeX patterns via an optional feature, though it adds binary size.

Provides procedural macros through the textwrap-macros crate for wrapping strings known at compile time, improving performance for static text.
