From dc477db757247d5184250bffe9dd0c38dd867778 Mon Sep 17 00:00:00 2001 From: Aleksey Kladov Date: Tue, 23 Oct 2018 19:15:31 +0300 Subject: Introduce ModuleId Previously, module was synonym with a file, and so a module could have had several parents. This commit introduces a separate module concept, such that each module has only one parent, but a single file can correspond to different modules. --- crates/ra_analysis/src/db.rs | 4 +- crates/ra_analysis/src/descriptors.rs | 282 ----------------------- crates/ra_analysis/src/descriptors/mod.rs | 63 +++++ crates/ra_analysis/src/descriptors/module/imp.rs | 146 ++++++++++++ crates/ra_analysis/src/descriptors/module/mod.rs | 176 ++++++++++++++ crates/ra_analysis/src/imp.rs | 145 ++++++------ crates/ra_analysis/src/lib.rs | 1 - crates/ra_analysis/src/roots.rs | 103 ++------- crates/ra_analysis/src/symbol_index.rs | 4 +- crates/ra_analysis/tests/tests.rs | 12 +- 10 files changed, 493 insertions(+), 443 deletions(-) delete mode 100644 crates/ra_analysis/src/descriptors.rs create mode 100644 crates/ra_analysis/src/descriptors/mod.rs create mode 100644 crates/ra_analysis/src/descriptors/module/imp.rs create mode 100644 crates/ra_analysis/src/descriptors/module/mod.rs diff --git a/crates/ra_analysis/src/db.rs b/crates/ra_analysis/src/db.rs index 956cbe162..b527cde61 100644 --- a/crates/ra_analysis/src/db.rs +++ b/crates/ra_analysis/src/db.rs @@ -12,7 +12,7 @@ use salsa;
