Struct FromBytesWithNulError

1.64.0 · Source
pub struct FromBytesWithNulError { /* private fields */ }
Expand description

An error indicating that a nul byte was not in the expected position.

The slice used to create a CStr must have one and only one nul byte, positioned at the end.

This error is created by the CStr::from_bytes_with_nul method. See its documentation for more.

§Examples

use std::ffi::{CStr, FromBytesWithNulError};

let _: FromBytesWithNulError = CStr::from_bytes_with_nul(b"f\0oo").unwrap_err();
