2018-12-12Rename `TokenStream::concat` and remove `TokenStream::concat_rc_vec`.Nicholas Nethercote-3/+3
`TokenStream::new` is a better name for the former, and the latter is now just equivalent to `TokenStream::Stream`.

2018-12-10reject invalid external doc attributesAndy Russell-2/+30
Also, provide a suggestion for the correct syntax.
2018-12-10Remove `tokenstream::Delimited`.Nicholas Nethercote-32/+31
Because it's an extra type layer that doesn't really help; in a couple of places it actively gets in the way, and overall removing it makes the code nicer. It does, however, move `tokenstream::TokenTree` further away from the `TokenTree` in `quote.rs`. More importantly, this change reduces the size of `TokenStream` from 48 bytes to 40 bytes on x86-64, which is enough to slightly reduce instruction counts on numerous benchmarks, the best by 1.5%. Note that `open_tt` and `close_tt` have gone from being methods on `Delimited` to associated methods of `TokenTree`.

2018-12-07use top level `fs` functions where appropriateAndy Russell-54/+47
This commit replaces many usages of `File::open` and reading or writing with `fs::read_to_string`, `fs::read` and `fs::write`. This reduces code complexity, and will improve performance for most reads, since the functions allocate the buffer to be the size of the file. I believe that this commit will not impact behavior in any way, so some matches will check the error kind in case the file was not valid UTF-8. Some of these cases may not actually care about the error.

2018-12-06Auto merge of #54517 - mcr431:53956-panic-on-include_bytes-of-own-file, ↵bors-7/+11
r=michaelwoerister 53956 panic on include bytes of own file fix #53956 When using `include_bytes!` on a source file in the project, compiler would panic on subsequent compilations because `expand_include_bytes` would overwrite files in the source_map with no source. This PR changes `expand_include_bytes` to check source_map and use the already existing src, if any.

2018-11-01Share empty `Vec`s more within `MatcherPos::matches`.Nicholas Nethercote-4/+9
`create_matches` creates a `Vec<Rc<Vec<NamedMatch>>>`. Even though all the inner `Vec`s are empty, each one is created separately. This commit changes `create_matches` so it instead creates one empty inner `Vec`, and shares it. The commit also changes `MatcherPos::matches` to a boxed slice, because its length doesn't change.
