Enum gfx_hal::pso::AllocationError

pub enum AllocationError {
    OutOfMemory(OutOfMemory),
    OutOfPoolMemory,
    FragmentedPool,
    IncompatibleLayout,
}

An error allocating descriptor sets from a pool.

Variants

OutOfMemory(OutOfMemory)

OutOfMemory::Host: Memory allocation on the host side failed. OutOfMemory::Device: Memory allocation on the device side failed. This could be caused by a lack of memory or pool fragmentation.

OutOfPoolMemory

Memory allocation failed as there is not enough in the pool. This could be caused by too many descriptor sets being created.

FragmentedPool

Memory allocation failed due to pool fragmentation.

IncompatibleLayout

Descriptor set allocation failed as the layout is incompatible with the pool.

Trait Implementations

impl Clone for AllocationError

fn clone(&self) -> AllocationError

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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, __formatter: &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.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<OutOfMemory> for AllocationError

fn from(source: OutOfMemory) -> Self

Performs the conversion.

impl PartialEq<AllocationError> for AllocationError

fn eq(&self, other: &AllocationError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &AllocationError) -> bool

This method tests for !=.
