edef 277e786d3f Panic when an unfinished Generator is dropped 2017-03-16 22:40:20 +01:00

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().
