Types

type Config

type Config struct {
	// Enables verbose error printing of all credential chain errors.
	// Should be used when wanting to see all errors while attempting to retreive
	// credentials.
	CredentialsChainVerboseErrors *bool

	// The credentials object to use when signing requests. Defaults to
	// a chain of credential providers to search for credentials in environment
	// variables, shared credential file, and EC2 Instance Roles.
	Credentials *credentials.Credentials

	// An optional endpoint URL (hostname only or fully qualified URI)
	// that overrides the default generated endpoint for a client. Set this
	// to `""` to use the default generated endpoint.
	//
	// @note You must still provide a `Region` value when specifying an
	//   endpoint for a client.
	Endpoint *string

	// The region to send requests to. This parameter is required and must
	// be configured globally or on a per-client basis unless otherwise
	// noted. A full list of regions is found in the "Regions and Endpoints"
	// document.
	//
	// @see http://docs.aws.amazon.com/general/latest/gr/rande.html
	//   AWS Regions and Endpoints
	Region *string

	// Set this to `true` to disable SSL when sending requests. Defaults
	// to `false`.
	DisableSSL *bool

	// The HTTP client to use when sending requests. Defaults to
	// `http.DefaultClient`.
	HTTPClient *http.Client

	// An integer value representing the logging level. The default log level
	// is zero (LogOff), which represents no logging. To enable logging set
	// to a LogLevel Value.
	LogLevel *LogLevelType

	// The logger writer interface to write logging messages to. Defaults to
	// standard out.
	Logger Logger

	// The maximum number of times that a request will be retried for failures.
	// Defaults to -1, which defers the max retry setting to the service specific
	// configuration.
	MaxRetries *int

	// Retryer guides how HTTP requests should be retried in case of recoverable failures.
	//
	// When nil or the value does not implement the request.Retryer interface,
	// the request.DefaultRetryer will be used.
	//
	// When both Retryer and MaxRetries are non-nil, the former is used and
	// the latter ignored.
	//
	// To set the Retryer field in a type-safe manner and with chaining, use
	// the request.WithRetryer helper function:
	//
	//   cfg := request.WithRetryer(aws.NewConfig(), myRetryer)
	//
	Retryer RequestRetryer

	// Disables semantic parameter validation, which validates input for missing
	// required fields and/or other semantic request input errors.
	DisableParamValidation *bool

	// Disables the computation of request and response checksums, e.g.,
	// CRC32 checksums in Amazon DynamoDB.
	DisableComputeChecksums *bool

	// Set this to `true` to force the request to use path-style addressing,
	// i.e., `http://s3.amazonaws.com/BUCKET/KEY`. By default, the S3 client will
	// use virtual hosted bucket addressing when possible
	// (`http://BUCKET.s3.amazonaws.com/KEY`).
	//
	// @note This configuration option is specific to the Amazon S3 service.
	// @see http://docs.aws.amazon.com/AmazonS3/latest/dev/VirtualHosting.html
	//   Amazon S3: Virtual Hosting of Buckets
	S3ForcePathStyle *bool

	// Set this to `true` to disable the EC2Metadata client from overriding the
	// default http.Client's Timeout. This is helpful if you do not want the EC2Metadata
	// client to create a new http.Client. This options is only meaningful if you're not
	// already using a custom HTTP client with the SDK. Enabled by default.
	//
	// Must be set and provided to the session.New() in order to disable the EC2Metadata
	// overriding the timeout for default credentials chain.
	//
	// Example:
	//    sess := session.New(aws.NewConfig().WithEC2MetadataDiableTimeoutOverride(true))
	//    svc := s3.New(sess)
	//
	EC2MetadataDisableTimeoutOverride *bool

	// be used to inspect request made and responses received.
	LogDebug
)
const (
	// LogDebugWithSigning states that the SDK should log request signing and
	// presigning events. This should be used to log the signing details of
	// requests for debugging. Will also enable LogDebug.
	LogDebugWithSigning LogLevelType = LogDebug | (1 << iota)

	// LogDebugWithHTTPBody states the SDK should log HTTP request and response

LogLevel returns the pointer to a LogLevel. Should be used to workaround not being able to take the address of a non-composite literal.

func (*LogLevelType) AtLeast

func (l *LogLevelType) AtLeast(v LogLevelType) bool

AtLeast returns true if this LogLevel is at least high enough to satisfies v. Is safe to use on nil value LogLevelTypes. If LogLevel is nill, will default to LogOff comparison.

func (*LogLevelType) Matches

func (l *LogLevelType) Matches(v LogLevelType) bool

Matches returns true if the v LogLevel is enabled by this LogLevel. Should be used with logging sub levels. Is safe to use on nil value LogLevelTypes. If LogLevel is nill, will default to LogOff comparison.

func (*LogLevelType) Value

func (l *LogLevelType) Value() LogLevelType

Value returns the LogLevel value or the default value LogOff if the LogLevel is nil. Safe to use on nil value LogLevelTypes.

type Logger

type Logger interface {
	Log(...interface{})
}

A Logger is a minimalistic interface for the SDK to log messages to. Should be used to provide custom logging writers for the SDK to use.

func NewDefaultLogger

func NewDefaultLogger() Logger

NewDefaultLogger returns a Logger which will write log messages to stdout, and use same formatting runes as the stdlib log.Logger

type LoggerFunc

type LoggerFunc func(...interface{})

A LoggerFunc is a convenience type to convert a function taking a variadic list of arguments and wrap it so the Logger interface can be used.

Example:

s3.New(sess, &aws.Config{Logger: aws.LoggerFunc(func(args ...interface{}) {
    fmt.Fprintln(os.Stdout, args...)
})})

func (LoggerFunc) Log

func (f LoggerFunc) Log(args ...interface{})

Log calls the wrapped function with the arguments provided

type ReaderSeekerCloser

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

ReaderSeekerCloser represents a reader that can also delegate io.Seeker and io.Closer interfaces to the underlying object if they are available.

func ReadSeekCloser

func ReadSeekCloser(r io.Reader) ReaderSeekerCloser

ReadSeekCloser wraps a io.Reader returning a ReaderSeekerCloser

func (ReaderSeekerCloser) Close

Close closes the ReaderSeekerCloser.

If the ReaderSeekerCloser is not an io.Closer nothing will be done.

func (ReaderSeekerCloser) Read

func (r ReaderSeekerCloser) Read(p []byte) (int, error)

Read reads from the reader up to size of p. The number of bytes read, and error if it occurred will be returned.

If the reader is not an io.Reader zero bytes read, and nil error will be returned.

Performs the same functionality as io.Reader Read

func (ReaderSeekerCloser) Seek

func (r ReaderSeekerCloser) Seek(offset int64, whence int) (int64, error)

Seek sets the offset for the next Read to offset, interpreted according to whence: 0 means relative to the origin of the file, 1 means relative to the current offset, and 2 means relative to the end. Seek returns the new offset and an error, if any.

If the ReaderSeekerCloser is not an io.Seeker nothing will be done.

type RequestRetryer

type RequestRetryer interface{}

RequestRetryer is an alias for a type that implements the request.Retryer interface.

type WriteAtBuffer

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

A WriteAtBuffer provides a in memory buffer supporting the io.WriterAt interface Can be used with the s3manager.Downloader to download content to a buffer in memory. Safe to use concurrently.

func (*WriteAtBuffer) Bytes

func (b *WriteAtBuffer) Bytes() []byte

Bytes returns a slice of bytes written to the buffer.

func (*WriteAtBuffer) WriteAt

func (b *WriteAtBuffer) WriteAt(p []byte, pos int64) (n int, err error)

WriteAt writes a slice of bytes to a buffer starting at the position provided The number of bytes written will be returned, or error. Can overwrite previous written slices if the write ats overlap.
