1//! This module handles fuzzy-searching of functions, structs and other symbols
2//! by name across the whole workspace and dependencies.
3//!
4//! It works by building an incrementally-updated text-search index of all
5//! symbols. The backbone of the index is the **awesome** `fst` crate by
6//! @BurntSushi.
7//!
8//! In a nutshell, you give a set of strings to `fst`, and it builds a
9//! finite state machine describing this set of strings. The strings which
10//! could fuzzy-match a pattern can also be described by a finite state machine.
11//! What is freaking cool is that you can now traverse both state machines in
12//! lock-step to enumerate the strings which are both in the input set and
13//! fuzz-match the query. Or, more formally, given two languages described by
14//! FSTs, one can build a product FST which describes the intersection of the
15//! languages.
16//!
17//! `fst` does not support cheap updating of the index, but it supports unioning
18//! of state machines. So, to account for changing source code, we build an FST
19//! for each library (which is assumed to never change) and an FST for each Rust
20//! file in the current workspace, and run a query against the union of all
21//! those FSTs.
