-//! Feature: completion with imports-on-the-fly
-//!
-//! When completing names in the current scope, proposes additional imports from other modules or crates,
-//! if they can be qualified in the scope, and their name contains all symbols from the completion input.
-//!
-//! To be considered applicable, the name must contain all input symbols in the given order, not necessarily adjacent.
-//! If any input symbol is not lowercased, the name must contain all symbols in exact case; otherwise the containing is checked case-insensitively.
-//!
-//! ```
-//! fn main() {
-//! pda$0
-//! }
-//! # pub mod std { pub mod marker { pub struct PhantomData { } } }
-//! ```
-//! ->
-//! ```
-//! use std::marker::PhantomData;
-//!
-//! fn main() {
-//! PhantomData
-//! }
-//! # pub mod std { pub mod marker { pub struct PhantomData { } } }
-//! ```
-//!
-//! Also completes associated items, that require trait imports.
-//! If any unresolved and/or partially-qualified path precedes the input, it will be taken into account.
-//! Currently, only the imports with their import path ending with the whole qualifier will be proposed
-//! (no fuzzy matching for qualifier).
-//!
-//! ```
-//! mod foo {
-//! pub mod bar {
-//! pub struct Item;
-//!
-//! impl Item {
-//! pub const TEST_ASSOC: usize = 3;
-//! }
-//! }
-//! }
-//!
-//! fn main() {
-//! bar::Item::TEST_A$0
-//! }
-//! ```
-//! ->
-//! ```
-//! use foo::bar;
-//!
-//! mod foo {
-//! pub mod bar {
-//! pub struct Item;
-//!
-//! impl Item {
-//! pub const TEST_ASSOC: usize = 3;
-//! }
-//! }
-//! }
-//!
-//! fn main() {
-//! bar::Item::TEST_ASSOC
-//! }
-//! ```
-//!
-//! NOTE: currently, if an assoc item comes from a trait that's not currently imported, and it also has an unresolved and/or partially-qualified path,
-//! no imports will be proposed.
-//!
-//! .Fuzzy search details
-//!
-//! To avoid an excessive amount of the results returned, completion input is checked for inclusion in the names only
-//! (i.e. in `HashMap` in the `std::collections::HashMap` path).
-//! For the same reasons, avoids searching for any path imports for inputs with their length less than 2 symbols
-//! (but shows all associated items for any input length).
-//!
-//! .Import configuration
-//!
-//! It is possible to configure how use-trees are merged with the `importMergeBehavior` setting.
-//! Mimics the corresponding behavior of the `Auto Import` feature.
-//!
-//! .LSP and performance implications
-//!
-//! The feature is enabled only if the LSP client supports LSP protocol version 3.16+ and reports the `additionalTextEdits`
-//! (case-sensitive) resolve client capability in its client capabilities.
-//! This way the server is able to defer the costly computations, doing them for a selected completion item only.
-//! For clients with no such support, all edits have to be calculated on the completion request, including the fuzzy search completion ones,
-//! which might be slow ergo the feature is automatically disabled.
-//!
-//! .Feature toggle
-//!
-//! The feature can be forcefully turned off in the settings with the `rust-analyzer.completion.autoimport.enable` flag.
-//! Note that having this flag set to `true` does not guarantee that the feature is enabled: your client needs to have the corresponding
-//! capability enabled.
