Overview ¶
Package memblob provides an in-memory blob implementation. Use OpenBucket to construct a *blob.Bucket.
URLs ¶
For blob.OpenBucket memblob registers for the scheme "mem". To customize the URL opener, or for more details on the URL format, see URLOpener. See https://gocloud.dev/concepts/urls/ for background information.
As ¶
memblob does not support any types for As.
Example (OpenBucketFromURL) ¶
package main
import (
"context"
"fmt"
"log"
"gocloud.dev/blob"
)
func main() {
// blob.OpenBucket creates a *blob.Bucket from a URL.
b, err := blob.OpenBucket(context.Background(), "mem://")
if err != nil {
log.Fatal(err)
}
defer b.Close()
// Now we can use b to read or write files to the container.
ctx := context.Background()
err = b.WriteAll(ctx, "my-key", []byte("hello world"), nil)
if err != nil {
log.Fatal(err)
}
data, err := b.ReadAll(ctx, "my-key")
if err != nil {
log.Fatal(err)
}
fmt.Println(string(data))
}
Output: hello world

Functions ¶
func OpenBucket ¶
OpenBucket creates a *blob.Bucket backed by memory.
Example ¶
package main
import (
"context"
"fmt"
"log"
"gocloud.dev/blob/memblob"
)
func main() {
// PRAGMA: This example is used on gocloud.dev; PRAGMA comments adjust how it is shown and can be ignored.
// PRAGMA: On gocloud.dev, hide lines until the next blank line.
ctx := context.Background()
// Create an in-memory bucket.
bucket := memblob.OpenBucket(nil)
defer bucket.Close()
// Now we can use bucket to read or write files to the bucket.
err := bucket.WriteAll(ctx, "my-key", []byte("hello world"), nil)
if err != nil {
log.Fatal(err)
}
data, err := bucket.ReadAll(ctx, "my-key")
if err != nil {
log.Fatal(err)
}
fmt.Println(string(data))
}
Output: hello world
Types ¶
type Options ¶
type Options struct {
// Set to true to disable MD5 hashing. The MD5 Attribute won't be available,
// but improves write performance.
NoMD5 bool
}
Options sets options for constructing a *blob.Bucket backed by memory.
