Struct HandleAllocator 

pub struct HandleAllocator { /* private fields */ }

Handle-based allocator with relocation support.

Implementations

impl HandleAllocator

pub fn new() -> Self

Create a new handle allocator.

pub fn alloc<T>(&self) -> Option<Handle<T>>

Allocate memory and return a handle.

pub fn alloc_with_options<T>( &self, relocatable: bool, on_relocate: Option<Box<dyn Fn(*mut u8, *mut u8) + Send + Sync>>, ) -> Option<Handle<T>>

Allocate with options.

pub fn free<T>(&self, handle: Handle<T>)

Free a handle.

pub fn resolve<T>(&self, handle: Handle<T>) -> Option<*const T>

Resolve a handle to a pointer.

Returns None if the handle is invalid or has been freed.

pub fn resolve_mut<T>(&self, handle: Handle<T>) -> Option<*mut T>

Resolve a handle to a mutable pointer.

pub fn is_valid<T>(&self, handle: Handle<T>) -> bool

Check if a handle is valid.

pub fn pin<T>(&self, handle: Handle<T>)

Pin a handle to prevent relocation.

pub fn unpin<T>(&self, handle: Handle<T>)

Unpin a handle to allow relocation.

pub fn defragment(&self) -> usize

Perform defragmentation by relocating memory.

This is a simple compaction that moves relocatable allocations to reduce fragmentation. Returns the number of relocations performed.

pub fn total_allocated(&self) -> u64

Get total allocated bytes.

pub fn active_count(&self) -> u32

Get number of active handles.

pub fn relocation_count(&self) -> u64

Get total relocations performed.

pub fn stats(&self) -> HandleAllocatorStats

Get statistics about the handle allocator.
