Struct InMemoryStorage 

pub struct InMemoryStorage { /* private fields */ }

In-memory storage: trials kept in a BTreeMap per study (ordered by trial number) behind a Mutex. Fast and dependency-free, but everything is lost when the process exits. This is the Phase 1–2 default.

impl Default for InMemoryStorage

fn default() -> InMemoryStorage

impl Storage for InMemoryStorage

fn save_trial( &self, study_name: &str, trial: &Trial, ) -> Result<(), StorageError>

Insert or update a trial for the given study.

fn load_trials(&self, study_name: &str) -> Result<Vec<Trial>, StorageError>

fn load_study_metadata( &self, study_name: &str, ) -> Result<Option<StudyMetadata>, StorageError>

Fetch study-level metadata, or None if the study is unknown.
