Variants

Construction

Variant

Construction(ConstructionError)

Checked host-side record construction failed before any native effects.

EnumerationUnstable

Variant

EnumerationUnstable

The native enumeration did not stabilize within the bounded retry budget.

InitializationFailed

Variant

InitializationFailed(InitializationFailure)

Native creation succeeded but cleanup could not be resolved. Handle this variant explicitly to recover the still-live object and retained library.

Vulkan

Variant

Vulkan(Result)

No public source comment is attached to this declaration.

MissingCommand

Variant

MissingCommand(&'static str)

No public source comment is attached to this declaration.

InvalidMetadata

Variant

InvalidMetadata(&'static str)

Invalid caller-supplied creation/import metadata; no native effect occurred.

FeatureNotEnabled

Variant

FeatureNotEnabled

A required exact feature-record member is disabled or unrecorded.

HostAllocationFailed

Variant

HostAllocationFailed

No public source comment is attached to this declaration.

InvalidOutput

Variant

InvalidOutput(&'static str)

No public source comment is attached to this declaration.

CountOverflow

Variant

CountOverflow(usize)

No public source comment is attached to this declaration.

SliceLengthMismatch

Variant

SliceLengthMismatch

An output/parallel slice does not match its native input count.

Methods and associated items

fmt

Method

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

Formats the value using the given formatter. Read more

fmt-1

Method

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

Formats the value using the given formatter. Read more

source

Method

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

Returns the lower-level source of this error, if any. Read more

from

Method

fn from(error: CallError) -> Self

Converts to this type from the input type.

from-1

Method

fn from(error: ConstructionError) -> Self

Converts to this type from the input type.

from-2

Method

fn from(r: Result) -> Self

Lift a non-success VkResult into a CallError.

Callers that only expect VK_SUCCESS can use ? on a vk::Result once it is inside a Result<_, CallError> context.

eq

Method

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

Tests for self and other values to be equal, and is used by ==.

Envk::load::CommandSupport

pub enum CommandSupport {
    Enabled,
    Disabled,
    RequiresPhysicalDevice,
}

Version/extension admission for one exact command spelling. This does not validate enabled feature bits, parameters or Vulkan valid usage.

Contract

Version/extension admission for one exact command spelling. This does not validate enabled feature bits, parameters or Vulkan valid usage.

Variants

Enabled

Variant

Enabled

No public source comment is attached to this declaration.

Disabled

Variant

Disabled

No public source comment is attached to this declaration.

RequiresPhysicalDevice

Variant

RequiresPhysicalDevice

An instance-level query depends on support on the selected physical device.

Methods and associated items

clone

Method

fn clone(&self) -> CommandSupport

Returns a duplicate of the value. Read more

fmt

Method

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

Formats the value using the given formatter. Read more

eq

Method

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

Tests for self and other values to be equal, and is used by ==.

Envk::load::CreatedHandle

pub enum CreatedHandle {
    Instance(InstanceHandle),
    Device(DeviceHandle),
}

A native object returned successfully before dispatch initialization failed.

Contract

A native object returned successfully before dispatch initialization failed.

Variants

Instance

Variant

Instance(InstanceHandle)

No public source comment is attached to this declaration.

Device

Variant

Device(DeviceHandle)

No public source comment is attached to this declaration.

Methods and associated items

clone

Method

eq

Method

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