- Add a small section to generics.md to explain how ambiguities in type
inference can be resolved using the ::<> syntax.
- Add links from syntax-index.md and iterators.md.
- Minor edits to iterators.md and structs.md.
Docs: Better explanation of return values for min, max functions for the Iterator trait
Added an explanation that `None` is returned if an iterator is empty.
Also added examples for `max` and `min`. I chose not to add examples for other functions like `max_by_key` etc. so that the examples stay concised and focused on the main functionality.
So I just encountered this error for the first time. It's unclear what
it means, why I encountered it, or how to fix it. But worst of all, it
has a random newline and weird indentation! This commit fixes that last
bit.
Fixup String::split_off documentation
1. Clarify that `String::split_off` returns one string and modifies self in-place. The documentation implied that it returns two new strings.
2. Make the documentation mirror `Vec::split_off`.
Correct a typo in procedural macros chapter of the Book.
A simple and short correction for procedural macros chapter of the Rust Programming Language Book.
erase late bound regions in `get_vtable_methods()`
Higher-ranked object types can otherwise cause late-bound regions to
sneak into the substs, leading to the false conclusion that some method
is unreachable.
r? @arielb1, who wrote the heart of this patch anyhow

[MIR] Make InlineAsm a Statement
Previously InlineAsm was an Rvalue, but its semantics doesn't really match the semantics of an
Rvalue - rather it behaves more like a Statement.
r? @nikomatsakis you wanted this to happen
rustc: Link statically to the MSVCRT
This commit changes all MSVC rustc binaries to be compiled with
`-C target-feature=+crt-static` to link statically against the MSVCRT instead of
dynamically (as it does today). This also necessitates compiling LLVM in a
different fashion, ensuring it's compiled with `/MT` instead of `/MD`.
cc #37406
The mx_handle_wait_* syscalls in Magenta were renamed to
mx_object_wait. The syscall is used in the Magenta/Fuchsia
implementation of std::process, to wait on child processes.
In addition, this patch enables the use of the system provided
libbacktrace library on Fuchsia targets. Symbolization is not yet
working, but at least it allows printing hex addresses in a backtrace
and makes building succeed when the backtrace feature is not disabled.
These are some samples that I have been focusing on improving over
time. In this PR, I mainly want to stem the bleeding where we in some
cases we show an error that gives you no possible way to divine the
problem.
Fix for bootstrapping on NixOS
NixOS puts Linux's dynamic loader in wierd place. Detect when we're on NixOS and patch the downloaded bootstrap executables appropriately.
appveyor: Move MSVC dist builds to their own builder
In the long run we want to separate out the dist builders from the test
builders. This provides us leeway to expand the dist builders with more tools
(e.g. Cargo and the RLS) without impacting cycle times.
Currently the Travis dist builders double-up the platforms they provide builds
for, so I figured we could try that out for MSVC as well. This commit adds a new
AppVeyor builder which runs a dist for all the MSVC targets:
* x86_64-pc-windows-msvc
* i686-pc-windows-msvc
* i586-pc-windows-msvc
If this takes too long and/or times out we'll need to split this up. In any case
we're going to need more capacity from AppVeyor no matter what becaue the two
pc-windows-gnu targets can't cross compile so we need at least 2 more builders
no matter what.
1. Clarify that `String::split_off` returns one string and modifies self
in-place. The documentation implied that it returns two new strings.
2. Make the documentation mirror `Vec::split_off`.
* Update bootstrap to recognize the cputype 'sparcv9' (used on Solaris)
* Change to never use -fomit-frame-pointer on Solaris or for sparc
* Adds rust target sparcv9-sun-solaris
Fixes#39901
