v0.22.0

0.22.0 "Vulcanite" (2023-04-05)

This is the first non-alpha release of Fe. Read our announcement for more details.

Features

• Support for tests.

  example:

  #test
  fn my_test() {
      assert 26 + 16 == 42
  }
  

  Tests can be executed using the test subcommand.

  example:

  $ fe test foo.fe (#807)

• Fixed broken trait orphan rule

  Fe has an orphan rule for Traits similar to Rust's that requires
  that either the trait or the type that we are implementing the trait for
  are located in the same ingot as the impl. This rule was implemented
  incorrectly so that instead of requiring them to be in the same ingot,
  they were required to be in the same module. This change fixes this
  so that the orphan rule is enforced correctly.
  (#863)

• address values can now be specified with a number literal, with no explicit
  cast. So instead of let t: address = address(0xfe), one can now write
  let t: address = 0xfe. This also means that it's possible to define const
  addresses: const SOME_KNOWN_CONTRACT: address = 0xfefefefe
  (#864)

Bugfixes

• Fixed resolving of generic arguments to associated functions.

  For example, this code would previously crash the compiler:

  ...
    // This function doesn't take self
    pub fn run_static<T: Computable>(_ val: T) -> u256 {
      return val.compute(val: 1000)
    }
  ...
  
  // Invoking it would previously crash the compiler
  Runner::run_static(Mac())
  ...
