Documentation

Overview

Package qldbsession provides the client and types for making API requests to QLDB Session.

The transactional data APIs for Amazon QLDB

See https://docs.aws.amazon.com/goto/WebAPI/qldb-session-2019-07-11 for more information on this service.

See qldbsession package documentation for more information. https://docs.aws.amazon.com/sdk-for-go/api/service/qldbsession/

Using the Client

To use QLDB Session with the SDK use the New function to create a new service client. With that client you can make API requests to the service. These clients are safe to use concurrently.

See the SDK's documentation for more information on how to use the SDK. https://docs.aws.amazon.com/sdk-for-go/api/

See aws.Config documentation for more information on configuring SDK clients. https://docs.aws.amazon.com/sdk-for-go/api/aws/#Config

See the QLDB Session client for more information on creating client for this service. https://docs.aws.amazon.com/sdk-for-go/api/service/qldbsession/#New

Types

type AbortTransactionRequest 

type AbortTransactionRequest struct {
	// contains filtered or unexported fields
}

Contains the details of the transaction to abort.

func (AbortTransactionRequest) String 

func (s AbortTransactionRequest) String() string

String returns the string representation

type AbortTransactionResult 

type AbortTransactionResult struct {
	// contains filtered or unexported fields
}

Contains the details of the aborted transaction.

type Client 

type Client struct {
	*aws.Client
}

Client provides the API operation methods for making requests to QLDB Session. See this package's package overview docs for details on the service.

The client's methods are safe to use concurrently. It is not safe to modify mutate any of the struct's properties though.

func New 

func New(config aws.Config) *Client

New creates a new instance of the client from the provided Config.

Example: 

// Create a client from just a config.
svc := qldbsession.New(myConfig)

func (*Client) SendCommandRequest 

func (c *Client) SendCommandRequest(input *SendCommandInput) SendCommandRequest

SendCommandRequest returns a request value for making API operation for Amazon QLDB Session.

Sends a command to an Amazon QLDB ledger. 

// Example sending a request using SendCommandRequest.
req := client.SendCommandRequest(params)
resp, err := req.Send(context.TODO())
if err == nil {
    fmt.Println(resp)
}
