1.0.0[−][src]Function std::char::from_u32
pub fn from_u32(i: u32) -> Option<char>
Converts a u32
to a char
.
Note that all char
s are valid u32
s, and can be cast 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 u32
s are valid
char
s. 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
