Function malachite_base::chars::crement::contiguous_range_to_char

pub fn contiguous_range_to_char(u: u32) -> Option<char>

Converts a u32 to a char; if all chars were arranged in ascending order, passing $u$ to this function would return the $u$th char.

This function is the inverse of char_to_contiguous_range. Every u32 between $0$ and $\mathrm{NUMBER\_OF\_CHARS} - 1$, inclusive, is mapped to a distinct char. Passing a larger u32 yields None.

Worst-case complexity

Constant time and additional memory.

Examples

use malachite_base::chars::crement::contiguous_range_to_char;
use std::char;

assert_eq!(contiguous_range_to_char(0), Some('\u{0}'));
assert_eq!(contiguous_range_to_char(97), Some('a'));
assert_eq!(contiguous_range_to_char(1112063), Some(char::MAX));
