// DeviceSubRequestApplyConfiguration represents a declarative configuration of the DeviceSubRequest type for use
// with apply.
//
// DeviceSubRequest describes a request for device provided in the
// claim.spec.devices.requests[].firstAvailable array. Each
// is typically a request for a single resource like a device, but can
// also ask for several identical devices.
//
// DeviceSubRequest is similar to Request, but doesn't expose the AdminAccess
// or FirstAvailable fields, as those can only be set on the top-level request.
// AdminAccess is not supported for requests with a prioritized list, and
// recursive FirstAvailable fields are not supported.
type DeviceSubRequestApplyConfiguration struct {
	// Name can be used to reference this subrequest in the list of constraints
	// or the list of configurations for the claim. References must use the
	// format <main request>/<subrequest>.
	//
	// Must be a DNS label.
	Name *string `json:"name,omitempty"`
	// DeviceClassName references a specific DeviceClass, which can define
	// additional configuration and selectors to be inherited by this
	// subrequest.
	//
	// A class is required. Which classes are available depends on the cluster.
	//
	// Administrators may use this to restrict which devices may get
	// requested by only installing classes with selectors for permitted
	// devices. If users are free to request anything without restrictions,
	// then administrators can create an empty DeviceClass for users
	// to reference.
	DeviceClassName *string `json:"deviceClassName,omitempty"`
	// Selectors define criteria which must be satisfied by a specific
	// device in order for that device to be considered for this
	// subrequest. All selectors must be satisfied for a device to be
	// considered.
	Selectors []DeviceSelectorApplyConfiguration `json:"selectors,omitempty"`
	// AllocationMode and its related fields define how devices are allocated
	// to satisfy this subrequest. Supported values are:
	//
	// - ExactCount: This request is for a specific number of devices.
	// This is the default. The exact number is provided in the
	// count field.
	//
	// - All: This subrequest is for all of the matching devices in a pool.
	// Allocation will fail if some devices are already allocated,
	// unless adminAccess is requested.
	//
	// If AllocationMode is not specified, the default mode is ExactCount. If
	// the mode is ExactCount and count is not specified, the default count is
	// one. Any other subrequests must specify this field.
	//
	// More modes may get added in the future. Clients must refuse to handle
	// requests with unknown modes.
	AllocationMode *resourcev1beta1.DeviceAllocationMode `json:"allocationMode,omitempty"`
	// Count is used only when the count mode is "ExactCount". Must be greater than zero.
	// If AllocationMode is ExactCount and this field is not specified, the default is one.
	Count *int64 `json:"count,omitempty"`
	// If specified, the request's tolerations.
	//
	// Tolerations for NoSchedule are required to allocate a
	// device which has a taint with that effect. The same applies
	// to NoExecute.
	//
	// In addition, should any of the allocated devices get tainted
	// with NoExecute after allocation and that effect is not tolerated,
	// then all pods consuming the ResourceClaim get deleted to evict
	// them. The scheduler will not let new pods reserve the claim while
	// it has these tainted devices. Once all pods are evicted, the
	// claim will get deallocated.
	//
	// The maximum number of tolerations is 16.
	//
	// This is a beta field and requires enabling the DRADeviceTaints
	// feature gate.
	Tolerations []DeviceTolerationApplyConfiguration `json:"tolerations,omitempty"`
	// Capacity define resource requirements against each capacity.
	//
	// If this field is unset and the device supports multiple allocations,
	// the default value will be applied to each capacity according to requestPolicy.
	// For the capacity that has no requestPolicy, default is the full capacity value.
	//
	// Applies to each device allocation.
	// If Count > 1,
	// the request fails if there aren't enough devices that meet the requirements.
	// If AllocationMode is set to All,
	// the request fails if there are devices that otherwise match the request,
	// and have this capacity, with a value >= the requested amount, but which cannot be allocated to this request.
	Capacity *CapacityRequirementsApplyConfiguration `json:"capacity,omitempty"`
	// DerivedAttributes defines a set of virtual attributes computed via CEL expressions
	// for each candidate device. These virtual attributes can be referenced in
	// `.devices.constraints` to align and match different devices (e.g., co-allocating
	// a GPU and a NIC on the same NUMA node) even if their drivers publish different
	// attributes. Derived attributes are not available via `device.attributes`
	// in the CEL environment when evaluating selector expressions.
	//
	// Derived attributes allow you to extract, transform, or normalize topology
	// information (such as extracting a NUMA index from a complex topology string or
	// renaming a vendor-specific attribute) into a common virtual attribute name at
	// scheduling time. The scheduler then evaluates these virtual attributes exactly
	// like static attributes when matching constraints.
	//
	// Every derived attribute defined in this list must be referenced by at least one
	// MatchAttribute or DistinctAttribute constraint in the `.devices.constraints` list.
	//
	// The maximum number of derived attributes is 32.
	//
	// This is an alpha field and requires enabling the DRADerivedAttributes
