Enum FromBytesWithNulError 

pub enum FromBytesWithNulError {
    InteriorNul {
        position: usize,
    },
    NotNulTerminated,
}

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();

Variants

1.88.0
InteriorNul

Data provided contains an interior nul byte at byte position.

Fields

position: usize

The position of the interior nul byte.

1.88.0
NotNulTerminated

Data provided is not nul terminated.
