Struct std::ffi::NulError 1.0.0[−][src]
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.
Examples
use std::ffi::{CString, NulError}; let _: NulError = CString::new(b"f\0oo".to_vec()).unwrap_err();Run
Implementations
impl NulError
[src]
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.
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);Run
