blob

type Blob ¶

type Blob interface {
	Put(key string, data []byte) error
	Get(key string) ([]byte, error) // returns os.ErrNotExist semantics when absent
	List(prefix string) ([]string, error)
	Delete(key string) error
}

type Local ¶

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

Local stores objects as files under a directory. Keys map to relative paths; any "../" traversal is rejected so a key can't escape the root.

func NewLocal(dir string) (*Local, error)

func (l *Local) Delete(key string) error

func (l *Local) Get(key string) ([]byte, error)

func (l *Local) List(prefix string) ([]string, error)

func (l *Local) Put(key string, data []byte) error

type S3 ¶

type S3 struct {
	// contains filtered or unexported fields
}

S3 is an S3-compatible object-storage backend implemented with stdlib only — no AWS SDK, so the binary stays single and static. It speaks plain HTTP with SigV4 signing, which works against AWS S3, Cloudflare R2, Tigris, Backblaze B2, and MinIO. This is the cold tier for the cloud: per-tenant prefixes, infinite history at pennies/GB.

func NewS3(endpoint, region, bucket, accessKey, secretKey, prefix string) (*S3, error)

func (s *S3) Delete(key string) error

func (s *S3) Get(key string) ([]byte, error)

func (s *S3) List(prefix string) ([]string, error)

func (s *S3) Put(key string, data []byte) error
