Enum PointerError

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

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.

InvalidType

A pointer previously lent but the type is not the same.

Utf8Error(Utf8Error)

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

TryReserveError(TryReserveError)

Trying to alloc memory, see [alloc::collections::TryReserveError].

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 Error for PointerError

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 From<TryReserveError> for PointerError

fn from(error: TryReserveError) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for PointerError

fn from(error: Utf8Error) -> Self

Converts to this type from the input type.

impl PartialEq for PointerError

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