Enum PallocError 

pub enum PallocError {
    NoBlockSpace,
    AlreadyAllocated,
    NotAllocated,
    SegmentingTail,
    OutOfMemory,
    NullPtr,
}

defines an error returned from either an allocation or a deallocation

Variants

NoBlockSpace

no space is left between the block heap start the next link of the chain.

AlreadyAllocated

the block has already been allocated to something else.

NotAllocated

no allocation has been made on this block yet so the operation cannot proceed.

SegmentingTail

cannot segment the last block (tail) of the linked list as it does not have a defined heap size.

OutOfMemory

no more blocks can be allocated without going outside of memory bounds.

NullPtr

given is zero or memory header controlling it is zero

Trait Implementations

impl Debug for PallocError

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

Formats the value using the given formatter.

impl PartialEq for PallocError

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