| 76 | // Feature: Fuzzy Completion and Autoimports | ||
| 77 | // | ||
| 78 | // When completing names in the current scope, proposes additional imports from other modules or crates, | ||
| 79 | // if they can be qualified in the scope and their name contains all symbols from the completion input | ||
| 80 | // (case-insensitive, in any order or places). | ||
| 81 | // | ||
| 82 | // ``` | ||
| 83 | // fn main() { | ||
| 84 | // pda<|> | ||
| 85 | // } | ||
| 86 | // # pub mod std { pub mod marker { pub struct PhantomData { } } } | ||
| 87 | // ``` | ||

| 89 | // ``` | ||
| 90 | // use std::marker::PhantomData; | ||

| 98 | // .Fuzzy search details | ||
| 99 | // | ||
| 100 | // To avoid an excessive amount of the results returned, completion input is checked for inclusion in the identifiers only | ||
| 101 | // (i.e. in `HashMap` in the `std::collections::HashMap` path), also not in the module indentifiers. | ||
| 102 | // | ||
| 103 | // .Merge Behaviour | ||
| 104 | // | ||
| 105 | // It is possible to configure how use-trees are merged with the `importMergeBehaviour` setting. | ||
| 106 | // Mimics the corresponding behaviour of the `Auto Import` feature. | ||
| 107 | // | ||
| 108 | // .LSP and performance implications | ||
| 109 | // | ||
| 110 | // LSP 3.16 provides the way to defer the computation of some completion data, including the import edits for this feature. | ||
| 111 | // If the LSP client supports the `additionalTextEdits` (case sensitive) resolve client capability, rust-analyzer computes | ||
| 112 | // the completion edits only when a corresponding completion item is selected. | ||
| 113 | // For clients with no such support, all edits have to be calculated on the completion request, including the fuzzy search completion ones, | ||
| 114 | // which might be slow. | ||
| 115 | // | ||
| 116 | // .Feature toggle | ||
| 117 | // | ||
| 118 | // The feature can be turned off in the settings with the `rust-analyzer.completion.enableExperimental` flag. | ||
