Struct vulkano::memory::MemoryRequirements

pub struct MemoryRequirements {
    pub size: DeviceSize,
    pub alignment: DeviceSize,
    pub memory_type_bits: u32,
    pub prefers_dedicated_allocation: bool,
    pub requires_dedicated_allocation: bool,
}

Represents requirements expressed by the Vulkan implementation when it comes to binding memory to a resource.

Fields

size: DeviceSize

Number of bytes of memory required.

alignment: DeviceSize

Alignment of the requirement buffer. The base memory address must be a multiple of this value.

memory_type_bits: u32

Indicates which memory types can be used. Each bit that is set to 1 means that the memory type whose index is the same as the position of the bit can be used.

prefers_dedicated_allocation: bool

Whether implementation prefers to use dedicated allocations (in other words, allocate a whole block of memory dedicated to this resource alone). This will be false if the device API version is less than 1.1 and the khr_get_memory_requirements2 extension is not enabled on the device.

requires_dedicated_allocation: bool

Whether implementation requires the use of a dedicated allocation (in other words, allocate a whole block of memory dedicated to this resource alone). This will be false if the device API version is less than 1.1 and the khr_get_memory_requirements2 extension is not enabled on the device.

Trait Implementations
