See the documentation on Docs.rs.

Examples

use mic::{answer, solve};

#[answer]
fn main() -> _ {
    1
}
// 1 → println!("{}", 1)

#[answer(yn("Yes", "No"))]
fn main() -> _ {
    true
}
// true → "Yes"
//      → println!("{}", "Yes")

#[answer(tuple(" "))]
fn main() -> _ {
    (42, "foo")
}
// (42, "foo") → "42 foo".to_owned()
//             → println!("{}", "42 foo".to_owned())

#[answer(join("\n"))]
fn main() -> _ {
    1..=3
}
// 1..=3 → "1\n2\n3".to_owned()
//       → println!("{}", "1\n2\n3".to_owned())

#[answer(matrix(" "))]
fn main() -> _ {
    vec![vec![1, 2], vec![3, 4]]
}
// vec![vec![1, 2], vec![3, 4]] → "1 2\n3 4".to_owned()
//                              → println!("{}", "1 2\n3 4".to_owned())

#[answer(join(" "), map(add(1)))]
fn main() -> _ {
    vec![0, 2, 4] // 0-based graph node indices
}
// vec![0, 2, 4] → { impl Iterator } ([1, 3, 5])
//               → "1 3 5".to_owned()
//               → println!("{}", "1 3 5".to_owned())

#[solve(join(" "))]
fn solve() -> _ {
    1..=3
}
// 1..=3 → "1 2 3".to_owned()

assert_eq!("1 2 3", solve());
