Expand description
Extracts and parses signed and unsigned integers from surrounding text and whitespace.
A common pattern in Advent of Code is to parse and return 123, 456 and 789 from input
resembling:
Lorem ipsum 123 dolor 456 sit 789 ametThis module provides two &str extension methods iter_signed and iter_unsigned. The
reason for the separate methods is that some Advent of Code inputs contain the - character
as a delimiter and this would cause numbers to be incorrectly parsed as negative.
