Struct Allocation 

pub struct Allocation { /* private fields */ }

One live native region. No implicit free, unmap, submission or wait in Drop.

Implementations

impl Allocation

pub fn handle(&self) -> DeviceMemory

pub fn offset(&self) -> u64

pub fn size(&self) -> u64

pub fn reserved_size(&self) -> u64

Native extent reserved to this region, including non-coherent atom padding.

pub fn memory_type_index(&self) -> u32

pub fn heap_index(&self) -> u32

pub fn is_host_coherent(&self) -> bool

pub fn is_host_visible(&self) -> bool

pub fn is_freed(&self) -> bool

pub fn mapped_range( &self, offset: u64, size: u64, ) -> Result<Option<MappedMemoryRange<'static>>, AllocError>

Translate an allocation-relative range to a native block range. This does not validate allocator liveness or establish a mapping.

Donor: VMA VmaAllocator_T::GetFlushOrInvalidateRange. Adaptation: checked arithmetic, no-op ranges, allocation-end exception.
