Function std::str::truncate_utf16_at_nul[src]
pub fn truncate_utf16_at_nul(v: &'a [u16]) -> &'a [u16]
Return a slice of v ending at (and not including) the first NUL
(0).
Example
fn main() { use std::str; // "abcd" let mut v = ['a' as u16, 'b' as u16, 'c' as u16, 'd' as u16]; // no NULs so no change assert_eq!(str::truncate_utf16_at_nul(v), v.as_slice()); // "ab\0d" v[2] = 0; assert_eq!(str::truncate_utf16_at_nul(v), &['a' as u16, 'b' as u16]); }use std::str; // "abcd" let mut v = ['a' as u16, 'b' as u16, 'c' as u16, 'd' as u16]; // no NULs so no change assert_eq!(str::truncate_utf16_at_nul(v), v.as_slice()); // "ab\0d" v[2] = 0; assert_eq!(str::truncate_utf16_at_nul(v), &['a' as u16, 'b' as u16]);
