Struct `FromVecWithNulError`

struct FromVecWithNulError { ... }

An error indicating that a nul byte was not in the expected position.

The vector used to create a CString must have one and only one nul byte, positioned at the end.

This error is created by the CString::from_vec_with_nul method. See its documentation for more.

Examples

use std::ffi::{CString, FromVecWithNulError};

let _: FromVecWithNulError = CString::from_vec_with_nul(b"f\0oo".to_vec()).unwrap_err();

Implementations

`impl FromVecWithNulError`

fn as_bytes(self: &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());

fn into_bytes(self: 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());
