Errors for allocator operations.

Variants

AllocFailed(Layout, Cause)

The underlying allocator failed to allocate using the given layout; see the contained cause.

The cause may or may not be accurate depending on the type and environment.

InvalidLayout(InvLayout)

The layout computed with the given size and alignment is invalid; see the contained reason.

InvalidAlign(AlignErr)

The given alignment was invalid; see the contained information.

ZeroSizedLayout(NonNull<u8>)

The given layout was zero-sized. The contained NonNull will be dangling and valid for the requested alignment.

This can, in many cases, be considered a success.

GrowSmallerNewLayout(usize, usize)

Attempted to grow to a smaller size.

ShrinkLargerNewLayout(usize, usize)

Attempted to shrink to a larger size.

ArithmeticError(ArithErr)

An arithmetic error.

Other(&'static str)

Any other kind of error, in the form of a string.

Trait Implementations

impl Clone for AllocError

fn clone(&self) -> AllocError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AllocError

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

Formats the value using the given formatter.

impl Display for AllocError

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

Formats the value using the given formatter.

impl PartialEq for AllocError

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