/// Acquire a permit and execute one or more database queries within a single transaction.
///
/// This macro takes a store as the first argument and a code block as the second.
///
/// Internally it acquires a permit, executes the given code block and then commits the transaction
/// before returning with the result of the code block.
///
/// ## Example
///
/// ```rust,ignore
/// tx!(store, {
///     store.set_cursor(&new_cursor).await?;
/// });
/// ```
