{"comments":[{"comment":{"id":3814613,"creator_id":655673,"post_id":1151108,"content":"The `collect`'s in the middle aren't necessary, neither is splitting by `\": \"`. Here's a simpler version\n\n```rust\nfn main() {\n let text = \"seeds: 79 14 55 13\\nwhatever\";\n let seeds: Vec<_> = text\n .lines()\n .next()\n .unwrap()\n .split_whitespace()\n .skip(1)\n .map(|x| x.parse::().unwrap())\n .collect();\n println!(\"seeds: {:?}\", seeds);\n}\n```\n\nIt is simpler to bang out a `[int(num) for num in text.splitlines()[0].split(' ')[1:]]` in Python, but that just shows the happy path with no error handling, and does a bunch of allocations that the Rust version doesn't. You can also get slightly fancier in the Rust version by collecting into a `Result` for more succinct error handling if you'd like.\n\nEDIT: Here's also a version using `anyhow` for error handling, and the aforementioned `Result` collecting:\n\n```rust\nuse anyhow::{anyhow, Result};\n\nfn main() -> Result<()> {\n let text = \"seeds: 79 14 55 13\\nwhatever\";\n let seeds: Vec = text\n .lines()\n .next()\n .ok_or(anyhow!(\"No first line!\"))?\n .split_whitespace()\n .skip(1)\n .map(str::parse)\n .collect::>()?;\n println!(\"seeds: {:?}\", seeds);\n Ok(())\n}\n```","removed":false,"published":"2024-02-01T18:29:40.594150Z","updated":"2024-02-01T20:12:15.623662Z","deleted":false,"ap_id":"https://midwest.social/comment/6754167","local":false,"path":"0.3814613","distinguished":false,"language_id":0},"creator":{"id":655673,"name":"m_f","avatar":"https://midwest.social/pictrs/image/866e62bf-05eb-4781-abb2-f9dd9597a745.gif","banned":false,"published":"2023-08-02T16:30:07.979465Z","actor_id":"https://midwest.social/u/m_f","local":false,"deleted":false,"matrix_user_id":"@m__f:matrix.org","bot_account":false,"instance_id":19},"post":{"id":1151108,"name":"What could go wrong trying to solve AoC in Rust?","url":"https://sh.itjust.works/pictrs/image/876a5a42-2338-4341-800f-78ac044ac566.png","body":"![signal-2024-02-01-19-47-41-855](https://sh.itjust.works/pictrs/image/2ec88868-b621-47a5-9247-b2eb30ff0c6a.jpeg)","creator_id":6678,"community_id":212,"removed":false,"locked":false,"published":"2024-02-01T16:50:08.537977Z","updated":"2024-02-01T16:53:50.659899Z","deleted":false,"nsfw":false,"thumbnail_url":"https://sh.itjust.works/pictrs/image/20fcc948-cff3-4d80-80af-32323113cb4f.jpeg","ap_id":"https://sh.itjust.works/post/13879509","local":false,"language_id":37,"featured_community":false,"featured_local":false},"community":{"id":212,"name":"programmer_humor","title":"Programmer Humor","description":"Welcome to Programmer Humor!\n\nThis is a place where you can post jokes, memes, humor, etc. related to programming!\n\nFor sharing awful code theres also [Programming Horror](https://programming.dev/c/programming_horror).\n\n## Rules\n- Keep content in english\n- No advertisements\n- Posts must be related to programming or programmer topics","removed":false,"published":"2023-06-12T23:22:30.213448Z","updated":"2023-08-11T17:48:04.343031Z","deleted":false,"nsfw":false,"actor_id":"https://programming.dev/c/programmer_humor","local":false,"icon":"https://programming.dev/pictrs/image/170721ad-9010-470f-a4a4-ead95f51f13b.png","banner":"https://programming.dev/pictrs/image/ab84fc81-cbba-4504-b55b-2c886fe2624f.png","hidden":false,"posting_restricted_to_mods":false,"instance_id":20,"visibility":"Public"},"counts":{"comment_id":3814613,"score":46,"upvotes":47,"downvotes":1,"published":"2024-02-01T18:29:40.594150Z","child_count":2},"creator_banned_from_community":false,"banned_from_community":false,"creator_is_moderator":false,"creator_is_admin":false,"subscribed":"NotSubscribed","saved":false,"creator_blocked":false},{"comment":{"id":3824373,"creator_id":6678,"post_id":1151108,"content":"Yeah I was trying to do something like reading the first line by getting an iterator and just looping through the other lines normally, since first line was kind of a special case but it got messy quick.
