Enum AllocError 

pub enum AllocError {
    InvalidParam,
    MemoryOverlap,
    NoMemory,
    NotAllocated,
}

The error type used for allocation operations.

Examples

use buddy_slab_allocator::AllocError;

fn handle_error(error: AllocError) {
    match error {
        AllocError::InvalidParam => eprintln!("Invalid parameters"),
        AllocError::MemoryOverlap => eprintln!("Memory regions overlap"),
        AllocError::NoMemory => eprintln!("Out of memory"),
        AllocError::NotAllocated => eprintln!("Double free detected"),
    }
}

Variants

InvalidParam

Invalid size or alignment (e.g. unaligned)

MemoryOverlap

Memory added by add_memory overlapped with existing memory

NoMemory

No enough memory to allocate

NotAllocated

Attempt to deallocate a memory region that was not allocated

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 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.
