class OpenPartitionIo

Defined at line 55 of file fidling/gen/sdk/fidl/fuchsia.paver/fuchsia.paver/cpp/fidl/fuchsia.paver/cpp/markers.h

Opens a `PartitionIo` session backed by block devices in the caller-provided `block_dir`.

Under the capability-delegated permission model, the paver component does not hold ambient

access to all system block partitions. Instead, the caller (such as `system-updater` or

`fastboot`) is responsible for routing the required block device capabilities into its own

namespace (for example, via a scoped `/block` or `/block/ota` directory exposed by `fshost`)

and passing `block_dir` to the paver for the duration of the `PartitionIo` session.

`block_dir` is expected to follow the `fshost` `/block` directory layout (see

https://fuchsia.dev/fuchsia-src/development/storage/storage-partition-routing): each entry

<entry

>/` is a subdirectory containing a `fuchsia.storage.block.Block` protocol node at

<entry

>/fuchsia.storage.block.Block`.

`partition_io` will be closed on error, with an epitaph provided on failure reason.
