Why does a newline character count as two keys in a BTreeMap?

QUESTION

Why does a newline character count as two keys in a BTreeMap?

Asked 2017-Oct-14 at 21:05

I'm creating a compression/decompression library in Rust using Huffman encoding. One of the first steps is creating a data structure that contains all unique characters and the number of occurrences. I'm starting with just a simple text file, and having issues related to newline 'characters'.

My first attempt at solving this problem was constructing a BTreeMap, essentially a key-value pair of unique characters and their occurrences, respectively. Unfortunately, a newline 'character' is \n, which I think is not being handled corrected due to being two characters. I then converted the BTreeMap into a Vec to order by value, but that didn't solve the newline issue.

Here's my initial attempt at my comp binary package. Calling the binary is done using cargo, and my sample file is reproduced at the end of this question:

No, it is not. A newline character (UTF-8 codepoint 0x0A) is a single character.

I think I need to newline character to be a key in my key-value pair, but it's currently two keys.

No, it is not. Such a thing cannot happen "accidentally" either. If we somehow had two keys, you would have to call insert twice; there's no built-in concept of a multi-key map.

All that's happening here is that a newline character is printed as... a newline!
