Function std_unicode::char::from_u32 1.0.0
[−]
[src]
pub fn from_u32(i: u32) -> Option<char>
Converts a u32 to a char.
Note that all chars are valid u32s, and can be casted to one with
as:
let c = '💯'; let i = c as u32; assert_eq!(128175, i);Run
However, the reverse is not true: not all valid u32s are valid
chars. from_u32() will return None if the input is not a valid value
for a char.
For an unsafe version of this function which ignores these checks, see
from_u32_unchecked().
Examples
Basic usage:
use std::char; let c = char::from_u32(0x2764); assert_eq!(Some('❤'), c);Run
Returning None when the input is not a valid char:
use std::char; let c = char::from_u32(0x110000); assert_eq!(None, c);Run
