Enum gfx_hal::device::CreationError

pub enum CreationError {
    OutOfMemory(OutOfMemory),
    InitializationFailed,
    MissingExtension,
    MissingFeature,
    TooManyObjects,
    DeviceLost,
}

Device creation errors during open.

Variants

OutOfMemory(OutOfMemory)

Out of either host or device memory.

InitializationFailed

Device initialization failed due to implementation specific errors.

MissingExtension

At least one of the user requested extensions if not supported by the physical device.

MissingFeature

At least one of the user requested features if not supported by the physical device.

Use features for checking the supported features.

TooManyObjects

Too many logical devices have been created from this physical device.

The implementation may only support one logical device for each physical device or lacks resources to allocate a new device.

DeviceLost

The logical or physical device are lost during the device creation process.

This may be caused by hardware failure, physical device removal, power outage, etc.

Trait Implementations

impl Clone for CreationError

fn clone(&self) -> CreationError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CreationError

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

Formats the value using the given formatter.

impl Display for CreationError

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

Formats the value using the given formatter.

impl Error for CreationError

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

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

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

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

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

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<CreationError> for CreationError

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

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

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

This method tests for !=.
