Native structure VkAllocationCallbacks.

Khronos reference: VkAllocationCallbacks

Fields

p_user_data: *mut c_void

Native field pUserData.

pfn_allocation: PFN_vkAllocationFunction

Native field pfnAllocation.

pfn_reallocation: PFN_vkReallocationFunction

Native field pfnReallocation.

pfn_free: PFN_vkFreeFunction

Native field pfnFree.

pfn_internal_allocation: PFN_vkInternalAllocationNotification

Native field pfnInternalAllocation.

pfn_internal_free: PFN_vkInternalFreeNotification

Native field pfnInternalFree.

Implementations

impl AllocationCallbacks

pub fn new() -> Self

Construct the record with its default native state.

pub unsafe fn set_user_data(self, value: *mut c_void) -> Self

Set native pointer pUserData explicitly. No borrow or extent is inferred.

Safety

The caller must establish pointee validity, extent, alignment, aliasing and the full native retention lifetime before using this record in a native call. Callback, external-object and nested-pointer contracts remain caller obligations.

pub fn set_pfn_allocation(self, value: PFN_vkAllocationFunction) -> Self

Set native field pfnAllocation without native effects.

pub fn set_pfn_reallocation(self, value: PFN_vkReallocationFunction) -> Self

Set native field pfnReallocation without native effects.

pub fn set_pfn_free(self, value: PFN_vkFreeFunction) -> Self

Set native field pfnFree without native effects.

pub fn set_pfn_internal_allocation( self, value: PFN_vkInternalAllocationNotification, ) -> Self

Set native field pfnInternalAllocation without native effects.

pub fn set_pfn_internal_free( self, value: PFN_vkInternalFreeNotification, ) -> Self

Set native field pfnInternalFree without native effects.

Trait Implementations

impl Clone for AllocationCallbacks

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AllocationCallbacks

impl Default for AllocationCallbacks

fn default() -> Self

Returns the “default value” for a type.
