Hi! My favorite programming language is:
fn you_guessed_it() -> impl Debug {
..=..=.. .. .. .. .. .. .. .. .. .. .. .. .. ..
..=.. ..=.. .. .. .. .. .. .. .. .. .. ..=.. ..
..=.. ..=.. ..=.. ..=.. .. ..=..=.. ..=..=..=..
..=..=.. .. ..=.. ..=.. ..=.. .. .. .. ..=.. ..
..=.. ..=.. ..=.. ..=.. .. ..=.. .. .. ..=.. ..
..=.. ..=.. ..=.. ..=.. .. .. ..=.. .. ..=.. ..
..=.. ..=.. .. ..=..=.. ..=..=.. .. .. ..=..=..
}here are some of my stuffs:
Custom #[derive] aliases. Write this:
#[derive(Debug, ..Ord, ..Copy)]
// ^^^^^^^^^^^^^
// aliases
struct User;which expands to this:
#[derive(Debug, PartialEq, Eq, PartialOrd, Ord, Copy, Clone)]
// ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
// expanded
struct User;
Ergonomic multi-line string literals, even composes with any macro like format!.
use docstr::docstr;
let hello_world_in_c: &'static str = docstr!(
/// #include <stdio.h>
///
/// int main(int argc, char **argv) {
/// printf("hello world\n");
/// return 0;
/// }
);
assert_eq!(hello_world_in_c, r#"#include <stdio.h>
int main(int argc, char **argv) {
printf("hello world\n");
return 0;
}"#)
Lets you define custom literals. Like literals for Duration:
#[culit]
fn main() {
assert_eq!(
100d + 11h + 8m + 7s,
Duration::from_secs(100 * 60 * 60 * 24)
+ Duration::from_secs(11 * 60 * 60)
+ Duration::from_secs(8 * 60)
+ Duration::from_secs(7)
);
}Fully custom, can be whatever you want. Like 10nzusize which produces NonZeroUsize and compile errors if it is 0.
Simplest crate in existence for terminal styles.
use simply_colored::*;
println!("{BLUE}{BOLD}Simply colored!")
Like Neofetch but for your country
