Types ¶
type CalculatorParameters ¶
type CalculatorParameters struct {
Action string `json:"action"`
X int `json:"x"`
Y int `json:"y"`
}
CalculatorParameters is used to serialize parameters to the calculator Lambda handler.
type FunctionWrapper ¶
FunctionWrapper encapsulates function actions used in the examples. It contains an AWS Lambda service client that is used to perform user actions.
func (FunctionWrapper) CreateFunction ¶
func (wrapper FunctionWrapper) CreateFunction(ctx context.Context, functionName string, handlerName string, iamRoleArn *string, zipPackage *bytes.Buffer) types.State
CreateFunction creates a new Lambda function from code contained in the zipPackage buffer. The specified handlerName must match the name of the file and function contained in the uploaded code. The role specified by iamRoleArn is assumed by Lambda and grants specific permissions. When the function already exists, types.StateActive is returned. When the function is created, a lambda.FunctionActiveV2Waiter is used to wait until the function is active.
func (FunctionWrapper) DeleteFunction ¶
func (wrapper FunctionWrapper) DeleteFunction(ctx context.Context, functionName string)
DeleteFunction deletes the Lambda function specified by functionName.
func (FunctionWrapper) GetFunction ¶
GetFunction gets data about the Lambda function specified by functionName.
func (FunctionWrapper) Invoke ¶
func (wrapper FunctionWrapper) Invoke(ctx context.Context, functionName string, parameters any, getLog bool) *lambda.InvokeOutput
Invoke invokes the Lambda function specified by functionName, passing the parameters as a JSON payload. When getLog is true, types.LogTypeTail is specified, which tells Lambda to include the last few log lines in the returned result.
func (FunctionWrapper) ListFunctions ¶
func (wrapper FunctionWrapper) ListFunctions(ctx context.Context, maxItems int) []types.FunctionConfiguration
ListFunctions lists up to maxItems functions for the account. This function uses a lambda.ListFunctionsPaginator to paginate the results.
func (FunctionWrapper) UpdateFunctionCode ¶
func (wrapper FunctionWrapper) UpdateFunctionCode(ctx context.Context, functionName string, zipPackage *bytes.Buffer) types.State
UpdateFunctionCode updates the code for the Lambda function specified by functionName. The existing code for the Lambda function is entirely replaced by the code in the zipPackage buffer. After the update action is called, a lambda.FunctionUpdatedV2Waiter is used to wait until the update is successful.
func (FunctionWrapper) UpdateFunctionConfiguration ¶
func (wrapper FunctionWrapper) UpdateFunctionConfiguration(ctx context.Context, functionName string, envVars map[string]string)
UpdateFunctionConfiguration updates a map of environment variables configured for the Lambda function specified by functionName.
type IncrementParameters ¶
IncrementParameters is used to serialize parameters to the increment Lambda handler.
type LambdaResultFloat ¶
type LambdaResultFloat struct {
Result float32 `json:"result"`
}
LambdaResultFloat is used to deserialize a float32 result from a Lambda handler.
type LambdaResultInt ¶
type LambdaResultInt struct {
Result int `json:"result"`
}
LambdaResultInt is used to deserialize an int result from a Lambda handler.
