Constant vk_mem_alloc::ffi::VmaAllocationCreateFlagBits_VMA_ALLOCATION_CREATE_MAPPED_BIT

pub const VmaAllocationCreateFlagBits_VMA_ALLOCATION_CREATE_MAPPED_BIT: VmaAllocationCreateFlagBits = 4;

\brief Set this flag to use a memory that will be persistently mapped and retrieve pointer to it.

Pointer to mapped memory will be returned through VmaAllocationInfo::pMappedData.

It is valid to use this flag for allocation made from memory type that is not HOST_VISIBLE. This flag is then ignored and memory is not mapped. This is useful if you need an allocation that is efficient to use on GPU (DEVICE_LOCAL) and still want to map it directly if possible on platforms that support it (e.g. Intel GPU).
