Pure-virtual interface to be implemented by a server.
This interface uses typed channels (i.e. |::fidl::ClientEnd
<
::fuchsia_storage_block::Block>|
and |::fidl::ServerEnd
<
::fuchsia_storage_block::Block>|).
Public Methods
void GetInfo (GetInfoCompleter::Sync & completer)Get information about the underlying block device.
void OpenSession (::fuchsia_storage_block::wire::BlockOpenSessionRequest * request, OpenSessionCompleter::Sync & completer)Opens a new FIFO-based session on the block device.
void OpenSessionWithOffsetMap (::fuchsia_storage_block::wire::BlockOpenSessionWithOffsetMapRequest * request, OpenSessionWithOffsetMapCompleter::Sync & completer)Opens a new FIFO-based session on the block device, providing a mapping which is
transparently applied to device offsets in block FIFO requests.
This interface is intended to be used internally between nested Block implementations, in
order to provide passthrough I/O. For example, a fixed partition map (e.g. GPT) will serve
a Block protocol for each partition, and will respond to OpenSession requests by calling
OpenSessionWithOffsetMap on the underlying block device, establishing itself as the source
for translating client block offsets (relative to the partition start) to absolute offsets.
The client can then communicate directly with the underlying block device, and the partition
offsets can be transparently applied to requests.
void GetTypeGuid (GetTypeGuidCompleter::Sync & completer)Gets the type GUID of the partition (if one exists).
If the partition has no type GUID, ZX_ERR_NOT_SUPPORTED is returned.
void GetInstanceGuid (GetInstanceGuidCompleter::Sync & completer)Gets the instance GUID of the partition (if one exists).
If the partition has no instance GUID, ZX_ERR_NOT_SUPPORTED is returned.
void GetName (GetNameCompleter::Sync & completer)Gets the name of the partition (if one exists).
If the partition has no name, ZX_ERR_NOT_SUPPORTED is returned.
void GetMetadata (GetMetadataCompleter::Sync & completer)Gets the metadata for the partition.
Fields may be absent if the partition doesn't have the given metadata.
void QuerySlices (::fuchsia_storage_block::wire::BlockQuerySlicesRequest * request, QuerySlicesCompleter::Sync & completer)Returns the number of contiguous allocated (or unallocated) vslices
starting from each vslice.
Returns ZX_ERR_NOT_SUPPORTED if the device is not a volume.
void GetVolumeInfo (GetVolumeInfoCompleter::Sync & completer)Returns the information about this volume and the volume manager it is embedded in.
Returns ZX_ERR_NOT_SUPPORTED if the device is not a volume.
void Extend (::fuchsia_storage_block::wire::BlockExtendRequest * request, ExtendCompleter::Sync & completer)Extends the mapping of this partition.
The ability to extend the partition is dependent on having sufficient free space on the
underlying device, having sufficient free slots for tracking the bytes in the volume
manager header, and the partition limit (see VolumeManager.SetPartitionLimit).
Returns ZX_ERR_NOT_SUPPORTED if the device is not a volume.
void Shrink (::fuchsia_storage_block::wire::BlockShrinkRequest * request, ShrinkCompleter::Sync & completer)Shrinks a virtual partition. Returns `ZX_OK` if ANY slices are
freed, even if part of the requested range contains unallocated slices.
Returns ZX_ERR_NOT_SUPPORTED if the device is not a volume.
void Destroy (DestroyCompleter::Sync & completer)Destroys the current volume, removing it from the VolumeManager, and
freeing all underlying storage. The connection to the volume is also closed.
Returns ZX_ERR_NOT_SUPPORTED if the device is not a volume.

Handler bind_handler (async_dispatcher_t * dispatcher)|bind_handler| returns a handler that binds incoming connections to this
server implementation.
The returned handler borrows the server instance.
The server must outlive the provided |dispatcher|. Only after
the dispatcher is shutdown will it be safe to destroy the servers.
The server should not be moved.
