Types

type Runtime

type Runtime interface {
	// Init loads the wasm file, and initialize the runtime environment
	Init(wasmFile string) error

	// GetObserveDataTags returns observed datatags of the wasm sfn
	GetObserveDataTags() []uint32

	// GetWantedTarget returns the wanted target of the wasm sfn
	GetWantedTarget() string

	// RunInit runs the init function of the wasm sfn
	RunInit() error

	// RunHandler runs the wasm application (request -> response mode)
	RunHandler(ctx serverless.Context) error

	// Close releases all the resources related to the runtime
	Close() error
}

Runtime is the abstract interface for wasm runtime

func NewRuntime

func NewRuntime(runtimeType string) (Runtime, error)

NewRuntime returns a specific wasm runtime instance according to the type parameter
