Start paring down std::str. Issue #855 2011-08-31 17:23:34 -05:00			`// error-pattern:precondition constraint (for example, uint::le(a, b)`
Serialize constraints in types (literal arguments still not supported) This involved, in part, changing the ast::def type so that a def_fn has a "purity" field. This lets the typechecker determine whether functions defined in other crates are pure. It also required updating some error messages in tests. As a test for cross-crate constrained functions, I added a safe_slice function to std::str (slice(), with one of the asserts replaced with a function precondition) and some test cases (various versions of fn-constraint.rs) that call it. Also, I changed "fn" to "pred" for some of the boolean functions in std::uint. 2011-06-20 19:29:54 -05:00			`use std;`
