Struct MemoryTypeSelector 

Source 
pub struct MemoryTypeSelector { /* private fields */ }
Expand description

Validated device memory properties and non-coherent atom size.

Implementations§

Source§

impl MemoryTypeSelector

Source

pub fn new( properties: PhysicalDeviceMemoryProperties, atom: u64, ) -> Result<Self, AllocError>

Source

pub fn find_memory_type( &self, request: &AllocRequest, ) -> Result<u32, AllocError>

Select a compatible type; preferred-bit ties retain the lower index.

Donor: VMA VmaAllocator_T::FindMemoryTypeIndex, required-bit test and missing-preferred-bit cost. Adaptation: checked metadata, no hidden usage policy.
