0.5.0 #

  • Released on: 21 December, 2012
  • Branched from master on: 4 December, 2015

  • ~900 changes, numerous bugfixes

    • Syntax changes

      • Removed <- move operator
      • Completed the transition from the #fmt extension syntax to fmt!
      • Removed old fixed length vector syntax - [T]/N
      • New token-based quasi-quoters, quote_tokens!, quote_expr!, etc.
      • Macros may now expand to items and statements
      • a.b() is always parsed as a method call, never as a field projection
      • Eq and IterBytes implementations can be automatically generated with #[deriving_eq] and #[deriving_iter_bytes] respectively
      • Removed the special crate language for .rc files
      • Function arguments may consist of any irrefutable pattern

    • Semantic changes

      • & and ~ pointers may point to objects
      • Tuple structs - struct Foo(Bar, Baz). Will replace newtype enums.
      • Enum variants may be structs
      • Destructors can be added to all nominal types with the Drop trait
      • Structs and nullary enum variants may be constants
      • Values that cannot be implicitly copied are now automatically moved without writing move explicitly
      • &T may now be coerced to *T
      • Coercions happen in let statements as well as function calls
      • use statements now take crate-relative paths
      • The module and type namespaces have been merged so that static method names can be resolved under the trait in which they are declared

    • Improved support for language features

      • Trait inheritance works in many scenarios
      • More support for explicit self arguments in methods - self, &self @self, and ~self all generally work as expected
      • Static methods work in more situations
      • Experimental: Traits may declare default methods for the implementations to use

    • Libraries

      • New condition handling system in core::condition
      • Timsort added to std::sort
      • New priority queue, std::priority_queue
      • Pipes for serializable types, `std::flatpipes'
      • Serialization overhauled to be trait-based
      • Expanded getopts definitions
      • Moved futures to std
      • More functions are pure now
      • core::comm renamed to oldcomm. Still deprecated
      • rustdoc and cargo are libraries now

    • Misc

      • Added a preliminary REPL, rusti
      • License changed from MIT to dual MIT/APL2
