Variables ¶
var ErrFirstArgNotString = errors.New("expected first arg to be type string")
ErrFirstArgNotString is returned when the first argument to Call is not a string.
var ErrFunctionNotProvided = errors.New("extension doesn't provide function")
ErrFunctionNotProvided is returned when an extension does not provide the requested function.
var ErrNoArgs = errors.New("expected at least 1 arg")
ErrNoArgs is returned when Call is invoked without any arguments.
var ErrTooManyArguments = errors.New("too many arguments")
ErrTooManyArguments is returned when a template function is called with more arguments than it accepts.
var ErrUnknownExtension = errors.New("unknown extension")
ErrUnknownExtension is returned when the requested extension is not registered.
Functions ¶

Types ¶
type ExtensionCaller ¶
type ExtensionCaller struct {
// contains filtered or unexported fields
}
ExtensionCaller calls extension functions.
type Host ¶
type Host struct {
// contains filtered or unexported fields
}
Host implements an extension host that handles registering extensions and executing them.
func (*Host) Close ¶ added in v1.26.0
Close terminates the extension host, which in turn stops all current native extensions.
func (*Host) GetExtensionCaller ¶
func (h *Host) GetExtensionCaller(ctx context.Context) (*ExtensionCaller, error)
GetExtensionCaller returns an extension caller that's aware of all extension functions.
func (*Host) RegisterExtension ¶
func (h *Host) RegisterExtension(ctx context.Context, source, name string, version *resolver.Version) error
RegisterExtension registers a ext from a given source and compiles/downloads it. A client is then created that is able to communicate with the ext.
func (*Host) RegisterInprocExtension ¶ added in v1.20.0
func (h *Host) RegisterInprocExtension(name string, ext apiv1.Implementation)
RegisterInprocExtension registers an extension that is implemented within the same process directly with the host. Please limit the use of this API for unit testing only!
