Struct AllocationInfo 

pub struct AllocationInfo {
    pub device_memory: DeviceMemory,
    pub offset: u64,
    pub size: u64,
    pub reserved_size: u64,
    pub memory_type_index: u32,
    pub heap_index: u32,
    pub memory_properties: MemoryPropertyFlags,
    pub mapped_pointer: Option<*mut c_void>,
    pub map_count: u32,
    pub native_size: u64,
    pub is_separate: bool,
    pub user_data: usize,
}

Checked binding and mapping snapshot of one live allocation.

Offsets and sizes are native bytes. size is the queried memory requirement, not necessarily the logical buffer size or a linear image’s pixel extent. Copying a snapshot does not retain its allocation, mapping or native objects. Query again after mapping changes; never use a saved pointer after unmap/free.

Fields

device_memory: DeviceMemory

offset: u64

size: u64

reserved_size: u64

Includes non-coherent atom padding reserved to a pooled region.

memory_type_index: u32

heap_index: u32

memory_properties: MemoryPropertyFlags

Actual selected memory properties, rather than requested preferences.

mapped_pointer: Option<*mut c_void>

Allocation-relative pointer, present only for this region’s mapping hold. Observing this pointer does not acquire a hold or authorize dereferencing it.

map_count: u32

Explicit mapping holds; persistent mapping is independent.

native_size: u64

Size of the backing native memory object, including other pooled regions.

is_separate: bool

Separate native storage rather than a pooled placement (not proof of native dedication).

user_data: usize

Opaque consumer metadata. No dereference or ownership is inferred.
