close

Close the previously opened session, releasing session-scoped resources.

Rust API

// sync_api
pub fn mudu_close(session_id: OID) -> RS<()> {
    /* ... */
}

// async_api
pub async fn mudu_close(session_id: OID) -> RS<()> {
    /* ... */
}

Conceptual signature

close(session_id: OID) -> ()

Parameters

• session_id — the OID returned by a previous open call.

Return value

• () on success.

Errors

• InvalidSession: the provided OID does not identify an open session.

Transaction semantics

• If a transaction is open when close is called, behavior depends on the host lifecycle (automatic commit or rollback).

• In MuduDB procedures, the kernel typically manages the transaction boundary around the procedure call.

Example

let oid = mudu_open()?;
// ... use oid ...
mudu_close(oid)?;

Notes

• Procedures must close sessions they explicitly open to avoid resource leaks.

• Do not use a closed OID after close; doing so yields InvalidSession.
