- `extra::json` didn't make the cut, because of `extra::json` required
dep on `extra::TreeMap`. If/when `extra::TreeMap` moves out of `extra`,
then `extra::json` could move into `serialize`
- `libextra`, `libsyntax` and `librustc` depend on the newly created
`libserialize`
- The extensions to various `extra` types like `DList`, `RingBuf`, `TreeMap`
and `TreeSet` for `Encodable`/`Decodable` were moved into the respective
modules in `extra`
- There is some trickery, evident in `src/libextra/lib.rs` where a stub
of `extra::serialize` is set up (in `src/libextra/serialize.rs`) for
use in the stage0 build, where the snapshot rustc is still making
deriving for `Encodable` and `Decodable` point at extra. Big props to
@huonw for help working out the re-export solution for this
extra: inline extra::serialize stub
fix stuff clobbered in rebase + don't reexport serialize::serialize
no more globs in libserialize
syntax: fix import of libserialize traits
librustc: fix bad imports in encoder/decoder
add serialize dep to librustdoc
fix failing run-pass tests w/ serialize dep
adjust uuid dep
more rebase de-clobbering for libserialize
fixing tests, pushing libextra dep into cfg(test)
fix doc code in extra::json
adjust index.md links to serialize and uuid library
- renames `Default` to `Show`
- introduces some hidden `std::fmt::secret_...` functions, designed to work-around the lack of UFCS (with UFCS they can be replaced by referencing the trait methods directly) because I'm going to convert the traits to have methods rather than static functions, since `#[deriving]` works much better with true methods.
I'm blocked on a snapshot after this. (I could probably do a large number of `#[cfg]`s, but I can work on other things in the meantime.)
This removes @[] from the parser as well as much of the handling of it (and `@str`) from the compiler as I can find.
I've just rebased @pcwalton's (already reviewed) `@str` removal (and fixed the problems in a separate commit); the only new work is the trailing commits with my authorship.
Closes#11967
This is has been obsolete for quite a while now (including a release),
so removing the special handling seems fine. (The error message is quite
good still anyway.)
Fixes#9580.
I tried a couple of different ways to squash this, and still don't think this is ideal, but I wanted to get it out for feedback.
Closes#5900Closes#9942
There are a few scenarios where the compiler tries to evaluate CastExprs without the corresponding types being available yet in the type context: https://github.com/mozilla/rust/issues/10618, https://github.com/mozilla/rust/issues/5900, https://github.com/mozilla/rust/issues/9942
This PR takes the approach of having eval_const_expr_partial's CastExpr arm fall back to a limited ast_ty_to_ty call that only checks for (a subset of) valid const types, when the direct type lookup fails. It's kind of hacky, so I understand if you don't want to take this as is. I'd need a little mentoring to get this into better shape, as figuring out the proper fix has been a little daunting. I'm also happy if someone else wants to pick this up and run with it.
This closes 5900 and 9942, but only moves the goalposts a little on 10618, which now falls over in a later phase of the compiler.
For the purpose of deciding whether to truncate or extend the right hand side of bit shifts, use the size of the element type for SIMD vector types.
Fix#11900.
It was possible to trigger a stack overflow in rustc because the routine used to verify enum representability,
type_structurally_contains, would recurse on inner types until hitting the original type. The overflow condition was when a different structurally recursive type (enum or struct) was contained in the type being checked.
I suspect my solution isn't as efficient as it could be. I pondered adding a cache of previously-seen types to avoid duplicating work (if enums A and B both contain type C, my code goes through C twice), but I didn't want to do anything that may not be necessary.
I'm a new contributor, so please pay particular attention to any unidiomatic code, misuse of terminology, bad naming of tests, or similar horribleness :)
Updated to verify struct representability as well.
Fixes#3008.
Fixes#3779.
`Times::times` was always a second-class loop because it did not support the `break` and `continue` operations. Its playful appeal (which I liked) was then lost after `do` was disabled for closures. It's time to let this one go.
