* Renamed str::split -> str::split_byte
* Renamed str::splitn -> str::splitn_byte
* Renamed str::split_func -> str::split
* Renamed str::split_char -> str::split_char
* Renamed str::split_chars_iter -> str::split_char_iter
* Added u8::is_ascii
* Fixed the behavior of str::split_str, so that it matches split_chars
and split (i.e. ["", "XXX", "YYY", ""] == split_str(".XXX.YYY.", "."))
* Fixed str::split_byte and str::splitn_byte so that they handle
splitting UTF-8 strings on a given UTF-8/ASCII byte and also handle ""
as the others do
It is now no longer needed to have a ty::ctxt to get at the contents
of a ty::t. The straight-forward approach of doing this, simply making
ty::t a box type, unfortunately killed our compiler performance (~15%
slower) through refcounting cost. Thus, this patch now represents
ty::t as an unsafe pointer, assuming that the ty::ctxt, which holds
these boxes alive, outlives any uses of the ty::t values. In the
current compiler this trivially holds, but it is does of course add a
new potential pitfall.
ty::get takes a ty::t and returns a boxed representation of the type.
I've changed calls to ty::struct(X) to do ty::get(X).struct. Type
structs are full of vectors, and copying them every time we wanted to
access them was a bit of a cost.
This allows a 'Name:' to appear in front of an iface declaration's
name, which will cause 'Name' to refer to the self type (with the same
number of type parameters as the iface has) in the method signatures
of the iface. For example:
iface F: functor<A> {
fn fmap<B>(f: fn(A) -> B) -> F<B>;
}
Issue #1718
Added class support to the parser, prettyprinter, fold, and visit.
(See Issue 1726.)
This is WIP -- the test case is xfailed, and attempting to compile
it will error out in resolve.
The direct motivation for this was that the monomorphizer needs to be
able to generate sane symbols for random items. The typechecker can
probably also use this in the future to provide more useful error
messages.
Now that core exports "option" as a synonym for option::t, search-and-
replace option::t with option.
The only place that still refers to option::t are the modules in libcore
that use option, because fixing this requires a new snapshot
(forthcoming).
This simplifies the typechecker a bit (no more ty_param_substs_opt_and_ty)
and is needed for another experiment I'm playing with. I hope it also
makes compilation faster (the bots will tell).
Remove disr_val from ast::variant_ and always use ty::variant_info
when the value is needed. Move what was done during parsing into
other passes, primary typeck.rs. This move also correctly type checks
the disr. value expression; thus, fixing rustc --pretty=typed when
disr. values are used.
Rather, it is now a struct where properties like opts are accessed
directly, and the error-reporting methods are part of a static impl
(with the same name as the type).
Use ifaces instead of objs, stop wrapping everything in two (or three)
layers of no-value-added indirection, and remove some of the more
pointless/outdated idioms from the code.
