Constant vk_mem_alloc::ffi::VmaAllocationCreateFlagBits_VMA_ALLOCATION_CREATE_HOST_ACCESS_RANDOM_BIT

pub const VmaAllocationCreateFlagBits_VMA_ALLOCATION_CREATE_HOST_ACCESS_RANDOM_BIT: VmaAllocationCreateFlagBits = 2048;

Requests possibility to map the allocation (using vmaMapMemory() or #VMA_ALLOCATION_CREATE_MAPPED_BIT).

• If you use #VMA_MEMORY_USAGE_AUTO or other VMA_MEMORY_USAGE_AUTO* value, you must use this flag to be able to map the allocation. Otherwise, mapping is incorrect.
• If you use other value of #VmaMemoryUsage, this flag is ignored and mapping is always possible in memory types that are HOST_VISIBLE. This includes allocations created in \ref custom_memory_pools.

Declares that mapped memory can be read, written, and accessed in random order, so a HOST_CACHED memory type is required.
