The BTreeSet and BTreeMap gdb pretty-printers did not take the node
structure into account, and consequently only worked for shallow sets.
This fixes the problem by iterating over child nodes when needed.
This patch avoids the current approach of implementing some of the
value manipulations in debugger-indepdendent code. This was done for
convenience: a type lookup was needed for the first time, and there
currently are no lldb formatters for these types.
Closes#55771
Without this, the `vis` does not wind up in the tree anywhere, and
then we get ICEs because the node-ids it refers to are not present.
The motivation seemed to be documentation, but `ListStem` HIR nodes
are ignored in rustdoc, from what I can tell.
Update books for Rust 2018
This PR:
1. updates all of the books
* I don't know if @Gankro has further plans for the nomicon or not
2. updates the build process because TRPL is only distributing one edition now
3. fixes up the stdlib links
I think that this passes but it's 3:20 am and so I'm sending it in and will fix up anything i missed in the morning.
/cc @alexcrichton for the big beta backport
resolve: Make "empty import canaries" invisible from other crates
Empty imports `use prefix::{};` are desugared into `use prefix::{self as _};` to make sure the prefix is checked for privacy/stability/etc.
This caused issues in cross-crate scenarios because gensyms are lost in crate metadata (the `_` is a gensym).
Fixes https://github.com/rust-lang/rust/issues/55811
The std::io::read main documentation can lead to error because the
buffer is prefilled with 10 zeros that will pad the response.
Using an empty vector is better.
The `read_to_end` documentation is already correct though.
This is my first rust PR, don't hesitate to tell me if I did something
wrong.
rustc: remove {FxHash,Node,DefId,HirId,ItemLocal}{Map,Set} "constructor" fns.
These are cruft left over from a time when `Foo::default()` didn't "just work".
