Stores Threadline exports on the local filesystem.
This is the default Threadline.Storage adapter. It is intended for a
single-node deployment whose filesystem is persistent and readable by the
web process. Select it explicitly when needed:
config :threadline, storage_adapter: Threadline.Storage.LocalFiles are stored under priv/threadline_exports. put/2 writes the supplied
binary content and accepts an optional :file_id; otherwise it generates a
CSV identifier. As an adapter-specific convenience, when the supplied binary
names an existing regular file, Local copies that file instead of storing the
path text. Other adapters are required to accept binary content only.
path/1 returns an expanded local path for export delivery. download_url/2
returns {:error, :not_supported} because this adapter does not generate
URLs. Filesystem failures are returned as {:error, reason} values from
Elixir's File module, while deleting a missing file is successful.
