parse_list for Rust

Parse files and lists of stringified things into lists of thingified things.

That is, if you've got something Read-y or Iterator-y over u8s, Strings, or strs, and a type that implements FromStr, you can also have an Iterator of that type of thing.

Particularly designed to parse files of newline-separated things, like these git integers:

0
1
2
3
4

Load your ints with ease:

// Create the file of test data
use std::fs;
let tmp_dir = TempDir::new("tmp").unwrap();
let file_path = tmp_dir.path().join("list");
fs::write(&file_path, "0\n1\n2\n3\n4").unwrap();

// Load from file. Note that each element could result in an individual
// I/O or parse error. Here those are converted into a single `Result<Vec<u32>, _>`.
let v = from_file_lines(&file_path);
let v: Vec<Result<u32, _>> = v.unwrap().collect();
let v: Result<Vec<u32>, _> = v.into_iter().collect();
let v = v.unwrap();
assert!(v == vec![0, 1, 2, 3, 4]);
