Struct SlotStorage

pub struct SlotStorage<'a> { /* private fields */ }

Represents a buffer of bytes that can be allocated from

This is similar to InlineStorage but because it doesnt store its buffer directly, it can potentially allocate memory with large alignments that are not known at compile time

Trait Implementations

impl Storage for SlotStorage<'_>

type Handle = SlotStorageHandle

The StorageHandle type that represents an allocation by this Storage

unsafe fn resolve(&self, handle: Self::Handle) -> NonNull<()>

Returns a pointer to the allocation represented by handle

fn allocate( &self, layout: Layout, ) -> Result<(Self::Handle, usize), StorageAllocError>

Allocates memory with a layout specified by layout

unsafe fn deallocate(&self, layout: Layout, handle: Self::Handle)

Deallocates (and invalidates) a StorageHandle that was allocated with this Storage

unsafe fn grow( &self, old_layout: Layout, new_layout: Layout, old_handle: Self::Handle, ) -> Result<(Self::Handle, usize), StorageAllocError>

Grows (increases the size of) an allocation

unsafe fn shrink( &self, old_layout: Layout, new_layout: Layout, old_handle: Self::Handle, ) -> Result<(Self::Handle, usize), StorageAllocError>

Shrinks (decreases the size of) an allocation
