Implementations

impl SessionMetadataService

pub async fn set_title( state: &AppState, session_id: &str, new_title: &str, ) -> Result<MetadataChange<(String, u64)>, MetadataError>

Manual rename via PATCH. Always authoritative; always bumps title_version and metadata_version. Returns Ok(None) when the trimmed input equals the existing title (no event emitted).

pub async fn apply_generated_title( state: &AppState, session_id: &str, candidate: &str, source: TitleSource, force: bool, ) -> Result<MetadataChange<(String, u64)>, MetadataError>

Auto/fallback rename produced by the title generator. Aborts (returns Ok(None)) if the on-disk session is no longer untitled and force is false — this guards against races where the user renames mid-LLM. On success bumps title_version and metadata_version, emits with the supplied TitleSource.

pub async fn set_pinned( state: &AppState, session_id: &str, pinned: bool, ) -> Result<MetadataChange<bool>, MetadataError>

Toggle the pinned flag. Returns Ok(None) if the requested value matches the current state (no event emitted). Bumps metadata_version.
