Function generic_str::from_utf8_mut [−][src]
Expand description
Converts a mutable slice of bytes to a mutable string slice.
Examples
Basic usage:
// "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 = generic_str::from_utf8_mut(&mut hellorust).unwrap();
assert_eq!(outstr, <&str>::from("Hello, Rust!"));
Incorrect bytes:
// Some invalid bytes in a mutable vector
let mut invalid = vec![128, 223];
assert!(generic_str::from_utf8_mut(&mut invalid).is_err());

errors that can be returned.
