Expand description
Fill a line of text at width
characters. Strings are wrapped
based on their displayed width, not their size in bytes.
The result is a string with newlines between each line. Use
wrap
if you need access to the individual lines or
wrap_iter
for its iterator counterpart.
use textwrap::fill;
assert_eq!(fill("Memory safety without garbage collection.", 15),
"Memory safety\nwithout garbage\ncollection.");
This function creates a Wrapper on the fly with default settings.
If you need to set a language corpus for automatic hyphenation, or
need to fill many strings, then it is suggested to create a Wrapper
and call its fill
method.
