Types

type Bucket

type Bucket struct {
	Name              string
	VersioningEnabled bool
	TimeCreated       time.Time
}

Bucket represents the bucket that is stored within the fake server.

type Error

type Error string

func (Error) Error

func (e Error) Error() string

type Object

type Object struct {
	ObjectAttrs
	Content []byte
}

Object represents the object that is stored within the fake server.

type ObjectAttrs

type ObjectAttrs struct {
	BucketName      string `json:"-"`
	Name            string `json:"-"`
	Size            int64  `json:"-"`
	ContentType     string
	ContentEncoding string
	Crc32c          string
	Md5Hash         string
	ACL             []storage.ACLRule
	Metadata        map[string]string
	Created         string
	Deleted         string
	Updated         string
	Generation      int64
}

ObjectAttrs represents the meta-data without its contents.

func (*ObjectAttrs) ID

func (o *ObjectAttrs) ID() string

ID is used for comparing objects.

func (*ObjectAttrs) IDNoGen

func (o *ObjectAttrs) IDNoGen() string

IDNoGen does not consider the generation field.

type Storage

type Storage interface {
	CreateBucket(name string, versioningEnabled bool) error
	ListBuckets() ([]Bucket, error)
	GetBucket(name string) (Bucket, error)
	DeleteBucket(name string) error
	CreateObject(obj Object) (Object, error)
	ListObjects(bucketName string, prefix string, versions bool) ([]ObjectAttrs, error)
	GetObject(bucketName, objectName string) (Object, error)
	GetObjectWithGeneration(bucketName, objectName string, generation int64) (Object, error)
	DeleteObject(bucketName, objectName string) error
	PatchObject(bucketName, objectName string, metadata map[string]string) (Object, error)
	UpdateObject(bucketName, objectName string, metadata map[string]string) (Object, error)
	ComposeObject(bucketName string, objectNames []string, destinationName string, metadata map[string]string, contentType string) (Object, error)
}

Storage is the generic interface for implementing the backend storage of the server.

func NewStorageFS

func NewStorageFS(objects []Object, rootDir string) (Storage, error)

NewStorageFS creates an instance of the filesystem-backed storage backend.

func NewStorageMemory

func NewStorageMemory(objects []Object) Storage

NewStorageMemory creates an instance of StorageMemory.
