Struct WorkspaceStore 

pub struct WorkspaceStore { /* private fields */ }

Persistent SavedQueryStore backed by the _hyperdb_saved_queries meta-table inside the .hyper workspace. Rows round-trip through SQL parameter binding so saved queries containing quotes or backslashes are handled safely.

Lazy init: the meta-table is created on the first save/list/get/ delete call, guarded by a Mutex<bool> so concurrent first-touches don’t race against each other.

Implementations

impl WorkspaceStore

pub fn new() -> Self

Construct an empty registry. The actual meta-table is created lazily on the first CRUD call.

Trait Implementations

impl Debug for WorkspaceStore

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

Formats the value using the given formatter.

impl Default for WorkspaceStore

fn default() -> WorkspaceStore

Returns the “default value” for a type.

impl SavedQueryStore for WorkspaceStore

fn save( &self, engine: Option<&Engine>, query: SavedQuery, ) -> Result<(), McpError>

Persist a new query. Returns an AlreadyExists-class error (currently SchemaMismatch, with a clear message) if name is already in use — callers should delete first if overwriting is intended.

fn get( &self, engine: Option<&Engine>, name: &str, ) -> Result<Option<SavedQuery>, McpError>

Retrieve a single saved query by name, or Ok(None) if not found.

fn list(&self, engine: Option<&Engine>) -> Result<Vec<SavedQuery>, McpError>

List all saved queries in alphabetical-by-name order. Empty workspaces return Ok(vec![]), never an error.

fn delete(&self, engine: Option<&Engine>, name: &str) -> Result<bool, McpError>

Remove a saved query by name. Returns Ok(false) if the name wasn’t present, Ok(true) if it was removed.
