Struct cstr_core::NulError[−][src]

pub struct NulError(_, _);
Expand description

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.

Examples

use cstr_core::{CString, NulError};

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

Implementations

Returns the position of the nul byte in the slice that was provided to CString::new.

Examples
use cstr_core::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.

Examples
use cstr_core::CString;

let nul_error = CString::new("foo\0bar").unwrap_err();
assert_eq!(nul_error.into_vec(), b"foo\0bar");
