#[aocd]Expand description
Annotate your main function with #[aocd(year, day)].
This sets up your main function so that you can use the aocd::input! and aocd::submit! macros.
You can optionally provide a third argument, a file name. If you do, this is treated as a
test-input, containing a smaller input that you want to test your code on before submitting.
In this case, the aocd::input! macro will read the input from that file instead of fetching
it from the website, and the aocd::submit! macro will just be a println alias.
§Example
ⓘ
use aocd::*;
#[aocd(2015, 1)]
fn main() {
let part_1_answer = input!().lines().len();
submit!(1, part_1_answer);
}ⓘ
use aocd::prelude::*; // Same as `use aocd::*;', but clippy allows it.
#[aocd(2015, 1, "test_input.txt")]
fn main() {
let part_1_answer = input!().lines().len(); // Reads from test_input.txt
submit!(1, part_1_answer); // Just prints the answer, doesn't submit it.
}§Panics
Panics (i.e. surfaces a compile error) if the arguments are not two integers in the expected ranges, or if the optional third argument is not a string literal containing a valid file name.
