 It's a parser combinators library, which essentially means that from some really basic functions you create more complex ones and keep building on top of it, until you have one final function that parses everything.

+Basically, when a parser correctly finishes, it returns a tuple with a slice starting where the parser ended and the parsed content. It seamlessly works with `&str` and `&[u8]` so most of the time you don't need to do any allocation when parsing.
 
 So `digit1("123therest")` returns a tuple with `("therest", "123")`.
 
 # Handling errors
 
-Since when parsing bencode there can be possible errors outside what the combinators may find, such as leading 0's on integers, we need to create our own error struct:
