pub fn as_bytes(&self) -> &[u8]
Returns a slice of u8s bytes that were attempted to convert to a CString.
Examples
Basic usage:
use std::ffi::CString;
// Some invalid bytes in a vector
let bytes = b"f\0oo".to_vec();
let value = CString::from_vec_with_nul(bytes.clone());
assert_eq!(&bytes[..], value.unwrap_err().as_bytes());1.58.0 · source
pub fn into_bytes(self) -> Vec<u8>
Returns the bytes that were attempted to convert to a CString.
This method is carefully constructed to avoid allocation. It will consume the error, moving out the bytes, so that a copy of the bytes does not need to be made.
Examples
Basic usage:
use std::ffi::CString;
// Some invalid bytes in a vector
let bytes = b"f\0oo".to_vec();
let value = CString::from_vec_with_nul(bytes.clone());
assert_eq!(bytes, value.unwrap_err().into_bytes());Recommend
