Types ¶
type Extensions ¶
type Extensions []string
Extensions represents a registry of extensions.
`internal` extensions are related to MicroCluster capabilities, not capabilities of MicroCluster-backed services.
To distinguish between `internal` and `external` extensions, `internal` extensions are prefixed with a `internal:` value. e.g, `internal:runtime_extension_v1`, `internal:runtime_extension_v2`, ...
External extensions are related to capabilities of MicroCluster-backed services. e.g, `microovn_custom_encapsulation_ip`
func NewExtensionRegistry ¶
func NewExtensionRegistry(populateInternal bool) (Extensions, error)
NewExtensionRegistry creates a new instance of the Extensions struct, which represents a registry of extensions. We have the option to populate the internal extensions or not. Having s option becomes handy when we want to create a custom registry of extensions (see `NewExtensionRegistryFromList`)
func NewExtensionRegistryFromList ¶
func NewExtensionRegistryFromList(extensions []string) (Extensions, error)
NewExtensionRegistryFromList creates a new instance of the Extensions struct, from a list of extensions. The passed extensions could be internal or external or just invalid. The function is typically used to create a registry from an API response in order to compare the source and the target systems' extensions for compatibility. The returned registry is always sorted with internal extensions first.
func (Extensions) HasExtension ¶
func (e Extensions) HasExtension(ext string) bool
HasExtension reports whether the extension set supports the given extension.
func (Extensions) IsSameVersion ¶
func (e Extensions) IsSameVersion(t Extensions) error
IsSameVersion checks if the source registry supports the target registry.
func (*Extensions) Register ¶
func (e *Extensions) Register(newExtensions []string) error
Register registers new external extensions to the Extensions struct.
func (*Extensions) Scan ¶
func (e *Extensions) Scan(value any) error
Scan implements the sql.Scanner interface to deserialize the Extensions struct from database storage.
func (Extensions) Value ¶
func (e Extensions) Value() (driver.Value, error)
Value implements the driver.Valuer interface to serialize the Extensions struct for database storage.
func (Extensions) Version ¶
func (e Extensions) Version() int
Version returns the number of extensions in the set, representing its version number.
