Enum StoreSpec 

pub enum StoreSpec {
    Memory,
    Fs,
}

Selects the transactor’s storage-service backend (blobs + roots).

Variants

Memory

In-memory blobs and roots; fully ephemeral and confined to one process. The transaction log is in memory too, so the whole database vanishes when the process exits — ideal for demos and tests.

Fs

Blobs and roots under {data_dir}/store, log under {data_dir}/logs.

Implementations

impl StoreSpec

pub fn from_connection( connection: StorageConnection, ) -> Result<(Self, PathBuf), StorageConnectionError>

Reconstructs a spec (and the filesystem data directory, empty for backends that carry their own location) from the connection info a transactor advertises through GetStorageInfo. The inverse of Self::connection_info, letting a client open the transactor’s storage service directly from just the transactor address.

Errors

Returns an error for a missing backend, an in-memory backend (confined to the transactor process), or a backend omitted from this build.

pub fn connection_info( &self, data_dir: &Path, ) -> Result<StorageConnection, String>

Describes how an administrative client can independently open this node’s storage service.

Local paths are made absolute because the client need not share the transactor’s working directory. The memory backend is described too, but cannot be opened by another process.

Errors

Returns an error when a local path cannot be represented on the wire.
