Functions

func Use

func Use(fn HandlerFunc) bridge

Use the provided HandlerFunc as handler for incoming requests. This function returns a bridge that manages values passing between the caller (python) and the target HandlerFunc.

Note: do not pass the bridge directly to C, otherwise CGo checker will complain, instead use a map of handles, see module/module.go for example.

Warning: bytes of eventData should be copied explicitly if you want to use them outside the HandlerFunc scope (e.g. in goroutines), they are valid until the Bridge func returns.

Types

type ClientContext

type ClientContext struct {
	InstallationID string `json:"installation_id"`
	AppTitle       string `json:"app_title"`
	AppVersionName string `json:"app_version_name"`
	AppVersionCode string `json:"app_version_code"`
	AppPackageName string `json:"app_package_name"`

	Custom json.RawMessage `json:"custom"`
	Env    json.RawMessage `json:"env"`
}

ClientContext holds information about the client application and device when invoked through the AWS Mobile SDK.

type CognitoIdentity

type CognitoIdentity struct {
	ID     string `json:"cognito_identity_id"`
	PoolID string `json:"cognito_identity_pool_id"`
}

CognitoIdentity identity provider when invoked through the AWS Mobile SDK.

type Context

type Context struct {
	FunctionName       string           `json:"function_name"`
	FunctionVersion    string           `json:"function_version"`
	InvokedFunctionARN string           `json:"invoked_function_arn"`
	MemoryLimitString  string           `json:"memory_limit_in_mb"`
	RequestID          string           `json:"aws_request_id"`
	LogGroupName       string           `json:"log_group_name"`
