// error-pattern:Predicate le(a, b) failed
use std;
import str::*;
import uint::le;

fn main() {
    let a: uint = 4u;
    let b: uint = 1u;
    check (le(a, b));
    log(error, safe_slice("kitties", 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 17:29:54 -07:00			`// error-pattern:Predicate le(a, b) failed`

Copy first batch of material from libstd to libcore. 2011-12-13 16:25:51 -08:00			`import str::*;`

Reformat for new syntax 2011-07-27 14:19:39 +02:00			`let a: uint = 4u;`
			`let b: uint = 1u;`
			`check (le(a, b));`
Register new snapshots, purge log_err and log_full in favour of log(...). 2011-12-22 17:53:53 -08:00			`log(error, safe_slice("kitties", a, b));`
Reformat This changes the indexing syntax from .() to [], the vector syntax from ~[] to [] and the extension syntax from #fmt() to #fmt[] 2011-08-19 15:16:48 -07:00			`}`
