  • Shorten 'mutable' to 'mut'
  • Required mutable-local qualifier: 'let mut ...'
  • Basic glob-exporting: 'export foo::*;'
  • Alt now exhaustive, 'alt check' for runtime-checked
  • Block-function form of 'for' loop, with 'break' and 'ret'.

• New library code

  • AST quasi-quote syntax extension

Rust 0.1

• Most language features work, including:

  • Unique pointers, unique closures, move semantics
  • Interface-constrained generics
  • Static interface dispatch
  • Stack growth
  • Multithread task scheduling
  • Typestate predicates
  • Failure unwinding, destructors
  • Pattern matching and destructuring assignment
  • Lightweight block-lambda syntax
  • Preliminary macro-by-example

• Compiler works with the following configurations:

  • Linux: x86 and x86_64 hosts and targets
  • macOS: x86 and x86_64 hosts and targets
  • Windows: x86 hosts and targets

• Cross compilation / multi-target configuration supported.

• Preliminary API-documentation and package-management tools included.

Known issues:

• Documentation is incomplete.

• Performance is below intended target.

• Standard library APIs are subject to extensive change, reorganization.

• Language-level versioning is not yet operational - future code will break unexpectedly.
