Struct ExportArgs 

pub struct ExportArgs {
    pub study: PathBuf,
    pub optuna: Option<PathBuf>,
    pub optuna_rdb: Option<PathBuf>,
}

atune export --optuna — write a study as an Optuna journal file.

The phase-0 GUI, with zero GUI code: the exported file is an Optuna journal-file op log, so optuna-dashboard <out.log> — or optuna.load_study(storage=JournalStorage(JournalFileBackend("<out.log>"))) — opens the atune study directly. See interoperating with Optuna.

Fields

study: PathBuf

The local study file (*.atj, *.db, *.sqlite, *.sqlite3) or atune://host:port remote observer endpoint to read.

Remote observer traffic is plaintext TCP: atune provides no authentication and no TLS. Use loopback, or a private VPN with host firewall and cloud/network ACLs; use an mTLS proxy where client identity is required. A private LAN alone is not an identity boundary.

Local Journal (*.atj) and SQLite (*.db, *.sqlite, *.sqlite3) data are plaintext. Require restrictive file permissions, an encrypted volume, and protected backups.

optuna: Option<PathBuf>

Write the Optuna journal to this path (omit, or -, for stdout).

--optuna PATH selects Optuna’s journal-file format and names the output. With neither --optuna nor --optuna-rdb, the journal goes to stdout; if only --optuna-rdb is given, nothing goes to stdout.

Export output is plaintext study data. Require restrictive file permissions, an encrypted volume, and protected backups.

optuna_rdb: Option<PathBuf>

Also write an Optuna RDB-sqlite database to this path.

Optuna’s relational on-disk form: optuna-dashboard sqlite:///<PATH> or optuna.load_study(storage="sqlite:///<PATH>") opens it. An existing file at PATH is replaced. May be combined with --optuna (each names its own output). Unlike --optuna, it has no stdout form — a database needs a path. The SQLite output is plaintext study data; require restrictive file permissions, an encrypted volume, and protected backups.

Trait Implementations

impl Args for ExportArgs

fn group_id() -> Option<Id>

Report the [ArgGroup::id][crate::ArgGroup::id] for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate Self via [FromArgMatches::from_arg_matches_mut]

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate self via [FromArgMatches::update_from_arg_matches_mut]

impl Debug for ExportArgs

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromArgMatches for ExportArgs

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.
