Textwrap

Textwrap is a small Rust crate for word wrapping strings. You can use it to format strings for display in commandline applications.

Strings are wrapped based on their displayed width, not their size in bytes. For ASCII characters such as a and !, the displayed with is the same as the number of bytes used to UTF-8 encode the character (one character takes up one byte). However, non-ASCII characters and symbols take up more than one byte: é is 0xc3 0xa9 and ⚙ is 0xe2 0x9a 0x99 in UTF-8, respectively. This means that relying solely on the string length in bytes would give incorrect results.
