edef df7f261ca6 Expose unsafe_unwrap
This at least ensures we don't have to needlessly leak generators in the
tests, and covers similar use cases for consumers of libfringe.

edef dcde4fe920 Don't use unsafe for the forget_yielded test
Now that the Send bound is gone, we can simply use a Cell instead of a
raw pointer.

edef 661872f725 Don't implement Send at all
On hosted platforms, libstd allows safely borrowing values from TLS with
'thread lifetime and without a Sync bound. As a result, we can't
guarantee that sending a generator across threads won't create dangling
references or data races. In freestanding environments, the notion of
thread-safety is likely to be defined by the consumer of libfringe,
so our Send bounds and implementation are unlikely to be meaningful
anyway.

edef 19ec5ef45b Make the passed Yielder borrow immutable [breaking-change]
Yielder::suspend only requires an immutable reference, and allowing
mem::replace on the yielder isn't very useful.

edef 59f28e92cb Ensure that the closure outlives the generator [breaking-change]
Previously, it was possible to cause unsafety by having the closure
refer to values with lifetimes that weren't enclosed by the generator's
lifetime.

whitequark 4b32c18f70 Rename Yielder::generate to Yielder::suspend.
This makes more sense, because "generate" implies *running*
a generator, not *returning* from a generator. That name was
a vestige of the time when libfringe only really provided a .next()
implementation, which made marginally more sense together with
.generate(), but it doesn't anymore when we have .resume().

edef b1a6b17d0a Move the Context tests and benches into src/
This concludes preparations for making Context private again.
2016-08-13 13:38:04 +02:00
whitequark 892a7696ec Allow unwinding to propagate across a context swap.
The main purpose of this is having nice backtraces in gdb, although
it also slightly simplifies poisoning state of the API consumers
after a panic.

whitequark 758088c673 Fix Stack::new(0). 2016-07-17 13:55:43 -04:00
whitequark ebd9ca8dec Allocate guard page under existing stack, not in it.
This fixes a segfault when the allocated stack is just one page long.

This also refactors the fringe::os module to use Result consistently.

edef bc184237cc rename simd -> context_simd
This fixes a spurious rustc warning.
2016-07-16 16:18:58 -04:00
whitequark cbe136b762 Completely rework fringe::Context and fringe::arch.
The new design concerns itself with one thing and exactly one thing:
passing values back and forth with an extern "C" function.
This allows to simplify fringe::arch into a single primitive, swap.
