Functions

func NameAndVersion

func NameAndVersion(component Component) string

NameAndVersion accepts a component and provids the canonical string representation of the component with its name and version

Types

type Component

type Component interface {
	// Name returns the component name
	Name() string

	// Source returns the component source
	Source() string

	// Version returns the component version
	Version() string

	// Type returns the component's static constant type
	Type() unikraft.ComponentType

	// Component returns the component's configuration
	Component() ComponentConfig

	// KConfigMenu returns the component's KConfig configuration menu which
	// returns all possible options for the component
	KConfigMenu() (*kconfig.KConfigFile, error)

	// KConfigValeus returns the component's set of file KConfig which is known
	// when the relevant component packages have been retrieved
	KConfigValues() (kconfig.KConfigValues, error)

	// PrintInfo displays the information about the component via the provided
	// iostream
	PrintInfo(*iostreams.IOStreams) error
}

Component is the abstract interface for managing the individual microlibrary

type ComponentConfig

type ComponentConfig struct {
	Name          string                `yaml:",omitempty" json:"-"`
	Version       string                `yaml:",omitempty" json:"version,omitempty"`
	Source        string                `yaml:",omitempty" json:"source,omitempty"`
	Configuration kconfig.KConfigValues `yaml:",omitempty" json:"kconfig,omitempty"`

	Extensions map[string]interface{} `yaml:",inline" json:"-"`
	// contains filtered or unexported fields
}

ComponentConfig is the shared attribute structure provided to all microlibraries, whether they are a library, platform, architecture, an application itself or the Unikraft core.
