Enum gpu_descriptor::AllocationError

pub enum AllocationError {
    OutOfDeviceMemory,
    OutOfHostMemory,
    Fragmentation,
}

AllocationError that may occur during descriptor sets allocation.

Variants

OutOfDeviceMemory

Backend reported that device memory has been exhausted.
Deallocating device memory or other resources 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.

Fragmentation

The total number of descriptors across all pools created
with flag CREATE_UPDATE_AFTER_BIND_BIT set exceeds max_update_after_bind_descriptors_in_all_pools Or fragmentation of the underlying hardware resources occurs.

Trait Implementations

impl Debug for AllocationError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for AllocationError

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for AllocationError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide(&'a self, req: &mut Demand<'a>)

🔬 This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<CreatePoolError> for AllocationError

fn from(err: CreatePoolError) -> Self

Converts to this type from the input type.
