Functions

func DefaultHandler

func DefaultHandler(ctx context.Context, req events.APIGatewayWebsocketProxyRequest) (resp events.APIGatewayProxyResponse, err error)

DefaultHandler is an AWS Lambda handler that uses default arguments, as it would in a real deployment environment. It can be invoked with lambda.Start(server.DefaultHandler).

func EnsureTable

func EnsureTable(ctx context.Context, db *dynamodb.DynamoDB, name string) error

EnsureTable creates the DynamoDB table if it does not exist. It is useful in test environments.

func Handle

func Handle(ctx context.Context, req events.APIGatewayWebsocketProxyRequest, args Args) (resp events.APIGatewayProxyResponse, err error)

Handle is the main entrypoint of the server logic. It looks similar to an AWS Lambda handler function signature, but has a final argument args, which can be used to configure external dependencies in test environments.

func LocalDB

func LocalDB() *dynamodb.DynamoDB

Types

type AIGameState

type AIGameState interface {
	// Score evaluates the desirability of a state from the perspective of the AI player.
	Score() float64

	// AITurn returns true if the next move will be performed by the AI player.
	AITurn() bool

	// MoveCount returns the number of moves possible in the current state.
	MoveCount() int

	// Move performs the move at the given index and returns the next state after the move.
	Move(int) AIGameState
}

AIGameState represents the state of a game and implements game domain-specific logic.

type APIGatewayManagementAPIClient

type APIGatewayManagementAPIClient interface {
	PostToConnectionWithContext(ctx aws.Context, input *apigatewaymanagementapi.PostToConnectionInput, opts ...request.Option) (*apigatewaymanagementapi.PostToConnectionOutput, error)
}

type APIGatewayManagementAPIClientFactory

type APIGatewayManagementAPIClientFactory func(events.APIGatewayWebsocketProxyRequestContext) APIGatewayManagementAPIClient

type Args

type Args struct {
	DB                                   *dynamodb.DynamoDB
	TableName                            string
	APIGatewayManagementAPIClientFactory APIGatewayManagementAPIClientFactory
}

Args represent external dependencies of the server, which may be replaced in test environments.
