New Features

  • Support integer const expression evaluation in Match Check inspection. Now this inspection can analyze complex constant arithmetic expressions and hexadecimal, octal or binary forms of integer literals. Should also fix false positive Unreachable pattern warnings when constants are used

  • Test runner improvements:
    • Provide run configuration to launch all tests/benches in the whole directory
    • Show line marker for tests marked with quickcheck attribute provided by quickcheck crate
    • Correctly handle multiple targets with the same names
    • Better navigation from test tool window to the corresponding test

  • Add missing fields quick fix allows defining field values interactively

  • Allow taking into account the corresponding trait items by Find usages action

  • Add Cargo Crate action to create a new Cargo crate in existing project (by @Kobzol)

  • Support label_break_value syntax. See the corresponding RFC for more details

  • Improve inspection suppression. Now Naming conventions and Deprecation inspections provide quick fixes to suppress the corresponding warning via allow(lint) attribute insertion

Fixes

  • New macro expansion engine improvements:
    • Disable highlighting, inspections and other analysis while macro expansion to speed up the whole expansion process
    • Fix progress bar hangs while macro expansion
    • Fix performance regression of name resolution. Now new macro expansion engine shouldn’t affect name resolution performance

  • Slightly optimize name resolution performance

  • Mark workspace target dir as excluded

  • Don’t show false positive Unresolved reference errors inside trait implementation

  • Don’t show parameter hints for unnamed fields (by @tuxxi)

  • Filter out redundant auto import candidates better. Now auto import quick fix provides a single variant to import for HashMap, HashSet and similar structs

  • Fix false positive Module is private error annotations when module have restricted visibility like pub(self)

  • Move plugin project settings from misc.xml to workspace.xml

  • Underscore imports don’t bring the corresponding names into the scope now

  • Fix name resolution of Self in structs and enums

  • Add non-public fields into completion suggestions if they are allowed

  • Parse paired brackets inside Rust doc link text properly (by @ArtsiomCh)

  • Provide completion for new keys like crate-type and incremental in Cargo.toml
