rustHow to convert a slice of bytes to a string in Rust?
To convert a slice of bytes to a string in Rust, you can use the std::str::from_utf8
function. This function takes a slice of bytes and returns a Result<&str, Utf8Error>
.
Example code
let bytes = [104, 101, 108, 108, 111];
let string = std::str::from_utf8(&bytes).unwrap();
Output example
hello
The code above does the following:
let bytes = [104, 101, 108, 108, 111];
- creates a byte array containing the ASCII codes for the charactersh
,e
,l
,l
, ando
.let string = std::str::from_utf8(&bytes).unwrap();
- calls thestd::str::from_utf8
function with the byte array as an argument, and assigns the result to thestring
variable. Theunwrap
method is used to convert theResult
into a&str
.
