pub struct NulError(_, _);
An error indicating that an interior nul byte was found.
While Rust strings may contain nul bytes in the middle, C strings can't, as that byte would effectively truncate the string.
This error is created by the new method on CString. See its documentation for more.
use std::ffi::{CString, NulError};
let _: NulError = CString::new(b"f\0oo".to_vec()).unwrap_err();impl NulError[src]
pub fn nul_position(&self) -> usize[src]
Returns the position of the nul byte in the slice that caused CString::new to fail.
use std::ffi::CString;
let nul_error = CString::new("foo\0bar").unwrap_err();
assert_eq!(nul_error.nul_position(), 3);
let nul_error = CString::new("foo bar\0").unwrap_err();
assert_eq!(nul_error.nul_position(), 7);pub fn into_vec(self) -> Vec<u8>ⓘNotable traits for Vec<u8>
impl Write for Vec<u8>
[src]
Consumes this error, returning the underlying vector of bytes which generated the error in the first place.
