Overview ¶
Package azure implements the create-only Destination for Azure Blob Storage. WORM is a container immutability policy (version-level immutability); writes are create-only via If-None-Match. Auth uses DefaultAzureCredential. There is no delete path.

Types ¶
type Backend ¶
type Backend struct {
// contains filtered or unexported fields
}
Backend is a create-only Azure Blob Destination.
func (*Backend) PutImmutable ¶
func (b *Backend) PutImmutable(ctx context.Context, key string, r io.Reader, _ int64, _ dest.Retention) (dest.PutResult, error)
PutImmutable uploads key create-only (If-None-Match: *); immutability is enforced by the container's immutability policy. Never overwrites, never deletes.
func (*Backend) VerifyWorm ¶
VerifyWorm checks the container has version-level immutability enabled. (Full policy-lock state needs the management plane; this is the data-plane signal.)
type Options ¶
type Options struct {
Account string // storage account (real Azure)
Container string
Endpoint string // override service URL; default https://<account>.blob.core.windows.net/
ConnectionString string // for Azurite or shared-key auth
}
Options configures the Azure Blob backend. Credentials come from DefaultAzureCredential (real Azure) or a connection string (emulator / shared key).
