Functions

func MeetsConstraints

func MeetsConstraints(filter *string, input DeviceAttributes) (bool, error)

func SemverLib

func SemverLib() cel.EnvOption

Types

type CompilationResult

type CompilationResult struct {
	Program     cel.Program
	Error       *apiservercel.Error
	Expression  string
	OutputType  *cel.Type
	Environment *cel.Env
}

CompilationResult represents a compiled expression.

func (CompilationResult) DeviceMatches

func (c CompilationResult) DeviceMatches(ctx context.Context, input DeviceAttributes) (bool, error)

type DeviceAttributes

type DeviceAttributes struct {
	// DriverName gets appended to any attribute which does not already have
	// a fully qualified name. If set, then it is also made available as
	// a string attribute.
	DriverName string
	Attributes []api.DeviceAttribute

	// CELSuffix gets appended to all attributes name in a CEL expression which are
	// not already fully qualified. Optional.
	//
	// TODO: remove this once we agree to require fully-qualified attribute names.
	CELSuffix string
}

DeviceAttributes defines the input values for a CEL selector expression.

	semver.Version
}

Semver provdes a CEL representation of a semver.Version.
