Function core::char::from_u32_unchecked 1.5.0[−][src]
pub unsafe fn from_u32_unchecked(i: u32) -> charExpand description
Converts a u32 to a char, ignoring validity.
Note that all chars are valid u32s, and can be cast to one with
as:
let c = '💯';
let i = c as u32;
assert_eq!(128175, i);RunHowever, the reverse is not true: not all valid u32s are valid
chars. from_u32_unchecked() will ignore this, and blindly cast to
char, possibly creating an invalid one.
Safety
This function is unsafe, as it may construct invalid char values.
For a safe version of this function, see the from_u32 function.
Examples
Basic usage:
use std::char;
let c = unsafe { char::from_u32_unchecked(0x2764) };
assert_eq!('❤', c);Run
