Enum DeallocationError 

pub enum DeallocationError {
    CorruptedMarker,
    DoubleFree,
    ImproperAlignment,
    LayoutError(LayoutError),
    NullPtr,
}

Errors returned by crate::free.

Variants

CorruptedMarker

The header matches neither marker: either memory corruption occurred, or the pointer was not produced by this crate.

DoubleFree

The allocation was already freed.

ImproperAlignment

The pointer is not properly aligned.

LayoutError(LayoutError)

The size stored in the header does not form a valid layout, which signals memory corruption.

NullPtr

The pointer is null.

Trait Implementations

impl Clone for DeallocationError

fn clone(&self) -> DeallocationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeallocationError

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

Formats the value using the given formatter.

impl Display for DeallocationError

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

Formats the value using the given formatter.

impl Eq for DeallocationError

impl Error for DeallocationError

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<DeallocationError> for ReallocationError

fn from(source: DeallocationError) -> Self

Converts to this type from the input type.

impl From<LayoutError> for DeallocationError

fn from(source: LayoutError) -> Self

Converts to this type from the input type.

impl PartialEq for DeallocationError

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