pub struct NulError(_, _);

An error returned from CString::new to indicate that a nul byte was found in the vector provided.

Methods

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);

Consumes this error, returning the underlying vector of bytes which generated the error in the first place.
