std::ffi::NulError
Struct std::ffi::NulError
pub struct NulError(_, _);
An error returned from CString::new to indicate that a nul byte was found in the vector provided.
Methods
impl NulError
[src]
fn nul_position(&self) -> usize
Returns the position of the nul byte in the slice that was provided to CString::new.
Examples
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); fn into_vec(self) -> Vec<u8>
Consumes this error, returning the underlying vector of bytes which generated the error in the first place.
Examples
use std::ffi::CString;
let nul_error = CString::new("foo\0bar").unwrap_err();
assert_eq!(nul_error.into_vec(), b"foo\0bar"); Trait Implementations
