//! # Initate a scan against all enqueued data.
//!
//! The [`ScanMgrApi`] allows userscripts to initiate scan operations
//! of all enqueued data against all activated scan engines. It exposes
//! a higher-level API than invoking all the dequeueing and scanning
//! operations manually.
//!
//! ## Userscript API
//!
//! This is a userscript API. The API's functionality is registered with
//! the Lua virtual machine, where userscripts can call into it.
//!
//! ## Examples
//!
//! For full API documentation, launch sscan in interactive mode and
//! enter `help 'scanmgr'`, or see [`topics::scanmgr`].
//!
//! [`topics::scanmgr`]: crate::userscript_api::help_system::topics::scanmgr
