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_utf8function with the byte array as an argument, and assigns the result to thestringvariable. Theunwrapmethod is used to convert theResultinto a&str.
