Documentation

Overview

Package fileblob provides a bucket implementation that operates on the local filesystem. This should not be used for production: it is intended for local development.

Blob names must only contain alphanumeric characters, slashes, periods, spaces, underscores, and dashes. Repeated slashes, a leading "./" or "../", or the sequence "/./" is not permitted. This is to ensure that blob names map cleanly onto files underneath a directory.

Functions

func NewBucket

func NewBucket(dir string) (*blob.Bucket, error)

NewBucket creates a new bucket that reads and writes to dir. dir must exist.

func OpenSqlBucket

func OpenSqlBucket(dir string) (*blob.Bucket, error)

NewBucket creates a new bucket that reads and writes to dir. dir must exist.

Types

type InfoDataWriter

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

func (InfoDataWriter) Close

func (w InfoDataWriter) Close() error

func (InfoDataWriter) Write

func (w InfoDataWriter) Write(p []byte) (n int, err error)

type Sqlbucket

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

func OpenSqlBucketDirect

func OpenSqlBucketDirect(dir string) (*Sqlbucket, error)

NewBucketDirect creates a new bucket that reads and writes to dir. dir must exist.

func (*Sqlbucket) Attributes

func (b *Sqlbucket) Attributes(ctx context.Context, key string, isUID bool) (*driver.ObjectAttrs, error)
