Struct drone_core::ffi::NulError [−][src]
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 drone_core::ffi::{CString, NulError}; let _: NulError = CString::new(b"f\0oo".to_vec()).unwrap_err();
Implementations
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 drone_core::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);
pub fn into_vec(self) -> Vec<u8>
[src]
Consumes this error, returning the underlying vector of bytes which generated the error in the first place.
Examples
use drone_core::ffi::CString; let nul_error = CString::new("foo\0bar").unwrap_err(); assert_eq!(nul_error.into_vec(), b"foo\0bar");
