std: Remove UnsafeArc

2014-05-20T01:12:18+00:00

This type has been superseded by Arc>. The UnsafeArc type is a relic of an era that has long since past, and with the introduction of liballoc the standard library is able to use the Arc smart pointer. With little need left for UnsafeArc, it was removed. All existing code using UnsafeArc should either be reevaluated to whether it can use only Arc, or it should transition to Arc> [breaking-change]

core: Remove the cast module

2014-05-11T08:13:02+00:00

This commit revisits the `cast` module in libcore and libstd, and scrutinizes all functions inside of it. The result was to remove the `cast` module entirely, folding all functionality into the `mem` module. Specifically, this is the fate of each function in the `cast` module. * transmute - This function was moved to `mem`, but it is now marked as #[unstable]. This is due to planned changes to the `transmute` function and how it can be invoked (see the #[unstable] comment). For more information, see RFC 5 and #12898 * transmute_copy - This function was moved to `mem`, with clarification that is is not an error to invoke it with T/U that are different sizes, but rather that it is strongly discouraged. This function is now #[stable] * forget - This function was moved to `mem` and marked #[stable] * bump_box_refcount - This function was removed due to the deprecation of managed boxes as well as its questionable utility. * transmute_mut - This function was previously deprecated, and removed as part of this commit. * transmute_mut_unsafe - This function doesn't serve much of a purpose when it can be achieved with an `as` in safe code, so it was removed. * transmute_lifetime - This function was removed because it is likely a strong indication that code is incorrect in the first place. * transmute_mut_lifetime - This function was removed for the same reasons as `transmute_lifetime` * copy_lifetime - This function was moved to `mem`, but it is marked `#[unstable]` now due to the likelihood of being removed in the future if it is found to not be very useful. * copy_mut_lifetime - This function was also moved to `mem`, but had the same treatment as `copy_lifetime`. * copy_lifetime_vec - This function was removed because it is not used today, and its existence is not necessary with DST (copy_lifetime will suffice). In summary, the cast module was stripped down to these functions, and then the functions were moved to the `mem` module. transmute - #[unstable] transmute_copy - #[stable] forget - #[stable] copy_lifetime - #[unstable] copy_mut_lifetime - #[unstable] [breaking-change]

Handle fallout in iter, option, result, and sync::arc

API changes: - UnsafeArc::newN() returns Vec>

librustc: Remove `~EXPR`, `~TYPE`, and `~PAT` from the language, except

2014-05-07T06:12:54+00:00

for `~str`/`~[]`. Note that `~self` still remains, since I forgot to add support for `Box` before the snapshot. How to update your code: * Instead of `~EXPR`, you should write `box EXPR`. * Instead of `~TYPE`, you should write `Box`. * Instead of `~PATTERN`, you should write `box PATTERN`. [breaking-change]

Replace most ~exprs with 'box'. #11779

Add debug_assert and debug_assert_eq macros

2014-05-02T02:07:40+00:00

I also switched some `assert!` calls over to `debug_assert!`. Closes #12049. RFC: 0015-assert

Replace all ~"" with "".to_owned()

std: Make ~[T] no longer a growable vector

2014-04-18T17:06:24+00:00

This removes all resizability support for ~[T] vectors in preparation of DST. The only growable vector remaining is Vec. In summary, the following methods from ~[T] and various functions were removed. Each method/function has an equivalent on the Vec type in std::vec unless otherwise stated. * slice::OwnedCloneableVector * slice::OwnedEqVector * slice::append * slice::append_one * slice::build (no replacement) * slice::bytes::push_bytes * slice::from_elem * slice::from_fn * slice::with_capacity * ~[T].capacity() * ~[T].clear() * ~[T].dedup() * ~[T].extend() * ~[T].grow() * ~[T].grow_fn() * ~[T].grow_set() * ~[T].insert() * ~[T].pop() * ~[T].push() * ~[T].push_all() * ~[T].push_all_move() * ~[T].remove() * ~[T].reserve() * ~[T].reserve_additional() * ~[T].reserve_exect() * ~[T].retain() * ~[T].set_len() * ~[T].shift() * ~[T].shrink_to_fit() * ~[T].swap_remove() * ~[T].truncate() * ~[T].unshift() * ~str.clear() * ~str.set_len() * ~str.truncate() Note that no other API changes were made. Existing apis that took or returned ~[T] continue to do so. [breaking-change]
