- Successful merges: Convert Intos to Froms. #42227, Update docs for Debug* structs. #29355 #42836, redox: symlink and readlink #42975, Ignore *.iml files #42994, Document unintuitive argument order for Vec::dedup_by relation #43041, Various minor cleanups to rustbuild #43042, Add a stability marker for core::cmp::Reverse.0 #43043, README: note how to enable debugging for rustc #43045
- Failed merges:
... which are IntelliJ IDEA module files. (`.idea` is IDEA project files.)
This adds docs for the Debug* structs as well as examples from the Formatter::debug_* methods, so that a user knows how to construct them. I added these examples as the builders module is not public and hence the debug_*_new() functions are not available to a user. r? @steveklabnik Review comments. Mainly adding in the links for all of the structs and functions. Remove rust tag on code blocks.
When trying to use dedup_by to merge some auxiliary information from removed elements into kept elements, I was surprised to observe that vec.dedup_by(same_bucket) calls same_bucket(a, b) where b appears before a in the vector, and discards a when true is returned. This argument order is probably a bug, but since it has already been stabilized, I guess we should document it as a feature and move on. (Vec::dedup also uses == with this unexpected argument order, but I figure that’s not important since == is expected to be symmetric with no side effects.) Signed-off-by: Anders Kaseorg <andersk@mit.edu>
Rename Build.{cargo, rustc} to {initial_cargo, initial_rustc}.
This makes later negation much easier to interpret.
Prevents accidental mistakes in not using the right verbosity by going to only config or flags.
Convert Intos to Froms. This is a resubmission of rust-lang#42129 without `impl<T> From<Vec<T>> for Box<[T]>`.

Document unintuitive argument order for Vec::dedup_by relation When trying to use `dedup_by` to merge some auxiliary information from removed elements into kept elements, I was surprised to observe that `vec.dedup_by(same_bucket)` calls `same_bucket(a, b)` where `b` appears before `a` in the vector, and discards `a` when true is returned. This argument order is probably a bug, but since it has already been stabilized, I guess we should document it as a feature and move on. (`Vec::dedup` also uses `==` with this unexpected argument order, but I figure that’s not important since `==` is expected to be symmetric with no side effects.)
…r=alexcrichton Various minor cleanups to rustbuild This is work I did before the migration to the new rustbuild. I'd prefer to land this first, before my other PR, to make the diff a little clearer. r? @alexcrichton
…Simulacrum Add a stability marker for core::cmp::Reverse.0 Closes rust-lang#43027
README: note how to enable debugging for rustc I got stuck on this for a bit, looking for a debug option in `./x.py build --help`. Diff without newline changes: Before: > Various other options are also supported, and are documented in the config file. After: > Various other options, such as enabling debug information, are also supported, and are documented in the config file.
