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);
