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

InteriorNul

Data provided contains an interior nul byte at byte position.

Fields

position: usize

The position of the interior nul byte.

NotNulTerminated

Data provided is not nul terminated.

Trait Implementations

fn clone(&self) -> FromBytesWithNulError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FromBytesWithNulError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for FromBytesWithNulError

fn eq(&self, other: &FromBytesWithNulError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
