Implement RandomAccessIterator (RAI) where possible, for Iterator adaptors such as Map, Enumerate, Peek, Skip, Take, Cycle, where the adapted iterator is already RAI, and for collections where it is relevant (ringbuf and bitv).
After discussion with thestinger, remove the RAI impl for VecMutIterator, we cannot soundly provide mutable access with this trait.
Implement Extendable everywhere FromIterator is already implemented.
Fixes issue #8108.
Implement RAI where possible for iterator adaptors such as Map,
Enumerate, Skip, Take, Zip, Cycle (all of the requiring that the adapted
iterator also implements RAI).
Drop the "Iterator" suffix for the the structs in std::iterator.
Filter, Zip, Chain etc. are shorter type names for when iterator
pipelines need their types written out in full in return value types, so
it's easier to read and write. the iterator module already forms enough
namespace.
Implement Clone and DeepClone for functions with 0 to 8 arguments. `extern fn()` is implicitly copyable so it's simple, except there is no way to implement it generically over #n function arguments.
Allows deriving of Clone on structs containing `extern "Rust" fn`.
r? @graydon Package IDs can now be of the form a/b/c#FOO, where (if a/b/c is
a git repository) FOO is any tag in the repository. Non-numeric
tags only match against package IDs with the same tag, and aren't
compared linearly like numeric versions.
While I was at it, refactored the code that calls `git clone`, and segregated build output properly for different packages.
With an expression like
static w : foo = foo { a:5, ..x };
Rust currently gives the error "constant contains unimplemented expression type". This branch implements support for constant structs with `..base`.

This fixes the recently introduced peak memory usage regression by
freeing the intermediate results as soon as they're not required
anymore instead of keeping them around for the whole compilation
process.

Adds a fence operation to close#8061
Also adds static initializers to for atomic types. Since the fields are private, you aren't able to have `static mut` variables that are an atomic type. Each atomic type's initializer starts at a 0-value (so unset for `AtomicFlag` and false for `AtomicBool`).
#7617
While the code that was there should've been perfectly fine (and seemingly is on linux at least) there seems to be some sort of weird interaction going on with statics and vectors. I couldn't get a smaller test case to reproduce that behaviour. The for loop in `rust::usage` seemingly just goes past the end of the vector thus getting garbage which it tries to pass to malloc somewhere down the line.
In any case, using a fixed length vector seems to mitigate this.
Good evening,
This is a superset of @MaikKlein's #7969 commit, that I've fixed up to compile. I had a couple commits I wanted to do on top of @MaikKlein's work that I didn't want to bitrot.
