Enum opaque_pointer::error::PointerError

pub enum PointerError {
    Null,
    Invalid,
    Utf8Error(Utf8Error),
}

Errors that can be detected by the functions of this crate.

Of course, invalid address can not be detected, then it’s unsafe yet.

Variants

Null

Invalid

A pointer that was not previously lent to the FFI user.

Utf8Error(Utf8Error)

Trying to convert to &str a C string which content is not valid UTF-8.

Trait Implementations

impl Debug for PointerError

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

Formats the value using the given formatter.

impl Display for PointerError

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

Formats the value using the given formatter.

impl Eq for PointerError

impl Error for PointerError

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Utf8Error> for PointerError

fn from(err: Utf8Error) -> Self

Performs the conversion.

impl PartialEq<PointerError> for PointerError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
