Enum gpu_alloc::AllocationError

source ·
pub enum AllocationError {
    OutOfDeviceMemory,
    OutOfHostMemory,
    NoCompatibleMemoryTypes,
    TooManyObjects,
}
Expand description

Enumeration of possible errors that may occur during memory allocation.

Variants§

§

OutOfDeviceMemory

Backend reported that device memory has been exhausted.
Deallocating device memory from the same heap may increase chance that another allocation would succeed.

§

OutOfHostMemory

Backend reported that host memory has been exhausted.
Deallocating host memory may increase chance that another allocation would succeed.

§

NoCompatibleMemoryTypes

Allocation request cannot be fulfilled as no available memory types allowed by Request.memory_types mask is compatible with request.usage.

§

TooManyObjects

Reached limit on allocated memory objects count.
Deallocating device memory may increase chance that another allocation would succeed. Especially dedicated memory blocks.

If this error is returned when memory heaps are far from exhausted Config should be tweaked to allocate larger memory objects.
