pub fn from_utf8_mut(v: &mut [u8]) -> Result<&mut str, Utf8Error>
Converts a mutable slice of bytes to a mutable string slice.
Basic usage:
use std::str;
// "Hello, Rust!" as a mutable vector
let mut hellorust = vec![72, 101, 108, 108, 111, 44, 32, 82, 117, 115, 116, 33];
// As we know these bytes are valid, we can use `unwrap()`
let outstr = str::from_utf8_mut(&mut hellorust).unwrap();
assert_eq!("Hello, Rust!", outstr);Incorrect bytes:
use std::str; // Some invalid bytes in a mutable vector let mut invalid = vec![128, 223]; assert!(str::from_utf8_mut(&mut invalid).is_err());
See the docs for Utf8Error for more details on the kinds of errors that can be returned.
