Macro from_iter

macro_rules! from_iter {
    ($($rem:tt)*) => { ... };
}

Makes a &'static str from an const iterator over &strs or chars

Example

Iterator over strings

use konst::string;

const S: &str = string::from_iter!(
    &["foo", "bar", "baz"],
        flat_map(|s| {
            // By value iteration over arrays isn't supported,
            // but by-reference iteration is supported
            &[*s, ", "]
        })
);

assert_eq!(S, "foo, bar, baz, ");

Iterator over chars

use konst::{iter, string};

const S: &str = string::from_iter!('a'..='z');

assert_eq!(S, "abcdefghijklmnopqrstuvwxyz");
