Struct vulkano::memory::MemoryRequirements

pub struct MemoryRequirements {
    pub size: DeviceSize,
    pub alignment: DeviceSize,
    pub memory_type_bits: u32,
    pub prefer_dedicated: 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.

prefer_dedicated: 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 khr_get_memory_requirements2 extension is not enabled on the device.

Note: As its name says, using a dedicated allocation is an optimization and not a requirement.
