Struct SessionStore 

pub struct SessionStore { /* private fields */ }

In-memory SavedQueryStore for ephemeral workspaces. Entries live in a Mutex<HashMap> and vanish when the server process exits.

Intentional: reusing the saved query registry across restarts would be surprising when the workspace itself is ephemeral, since the underlying tables aren’t persisted either.

Implementations

impl SessionStore

pub fn new() -> Self

Construct an empty registry. Prefer wrapping in Arc immediately — both the tool router and the resource handler need a handle.

Trait Implementations

impl Debug for SessionStore

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

Formats the value using the given formatter.

impl Default for SessionStore

fn default() -> SessionStore

Returns the “default value” for a type.

impl SavedQueryStore for SessionStore

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.
