IntelliJ Rust Changelog #119

New Features

#4936 Provide name resolution of items declared in impl blocks for type aliases. Taking performance into account, this feature is only enabled for types with a limited number of aliases
#5087 Provide the quick fix for Mismatched types error annotation to change a function’s return type. Note, it doesn’t work inside trait impl blocks for now
#5124 Now “Unresolved reference” inspection highlights code more precisely (by @Exidex)
#5120 Detect E0451 compiler error
#5114 Annotate slice patterns as an experimental feature for toolchains before 1.42
Parser improvements:
- #5115 Support const trait impls syntax
- #5099 Parse paths in attributes correctly
- #5081 Correctly parse &raw operator. Note, type inference for the operator is not implemented yet
- #5009 Fix parsing of lifetime bounds in Fn trait types (by @rrevenantt)

#5101 Slightly speeds up macro expansion process when the experimental engine is enabled
#5085 Slightly speeds up cfg attributes processing

#5084 Prevent an infinite recursion while analyzing a control flow inside macros
#5082 Now some inspections (e.g., Liveness Analysis) correctly process macro calls. It should fix some false positive annotations
#5057 Now formatter adds a new line between items inside a function’s body
#5053 Fix “Introduce Variable” intention in case if the first expression is inside a nested block
#5020 Handle type aliases in “Destructure” intention (by @Kobzol)
#5012 Handle async functions in “Extract Function” refactoring (by @Kobzol)
#5103 Generates external documentation link for a public item from impl block even if it is located in a private module
