From e98aff109a1c4bda6a05f16981898425c302aa0c Mon Sep 17 00:00:00 2001 From: Steffen Lyngbaek Date: Tue, 10 Mar 2020 00:55:46 -0700 Subject: Parameter inlay hint separate from variable type inlay? #2876 Add setting to allow enabling either type inlay hints or parameter inlay hints or both. Group the the max inlay hint length option into the object. - Add a new type for the inlayHint options. - Add tests to ensure the inlays don't happen on the server side --- crates/ra_ide/Cargo.toml | 1 + crates/ra_ide/src/inlay_hints.rs | 101 ++++++++++++++++++++++++++++++++------- crates/ra_ide/src/lib.rs | 5 +- 3 files changed, 88 insertions(+), 19 deletions(-) (limited to 'crates/ra_ide') diff --git a/crates/ra_ide/Cargo.toml b/crates/ra_ide/Cargo.toml index 7235c944c..486832529 100644 --- a/crates/ra_ide/Cargo.toml +++ b/crates/ra_ide/Cargo.toml @@ -21,6 +21,7 @@ rustc-hash = "1.1.0" rand = { version = "0.7.3", features = ["small_rng"] } ra_syntax = { path = "../ra_syntax" } +ra_project_model = { path = "../ra_project_model" } ra_text_edit = { path = "../ra_text_edit" } ra_db = { path = "../ra_db" } ra_ide_db = { path = "../ra_ide_db" } diff --git a/crates/ra_ide/src/inlay_hints.rs b/crates/ra_ide/src/inlay_hints.rs index cf0cbdbd0..0f1c13c14 100644 --- a/crates/ra_ide/src/inlay_hints.rs +++ b/crates/ra_ide/src/inlay_hints.rs @@ -3,6 +3,7 @@ use hir::{Adt, HirDisplay, Semantics, Type};
