rustfmt and RLS compile-from-source errors error[E0308]: mismatched types #78958

Grommish · 2020-11-11T22:37:31Z

When building Rust from source (master@b2d115f6db5172c961dfeb50de15f35784dbc7c9), when compiling with x.py --config ./config.toml dist cargo extended library/std llvm-tools miri rust-dev rustc-dev src src/librustc src/lldb_batchmode.py src/tool /build-manifest

Building with the following ./configure flags:

jyn514 · 2020-11-11T23:43:46Z

RLS not building is a duplicate of #78078. Not sure why rustfmt isn't building, it's available on the latest nightly.

jyn514 · 2020-11-11T23:47:12Z

Rustfmt was fixed in #78775, please rebase over the latest version of master.

Grommish · 2020-11-12T00:11:07Z

Thank you @jyn514 ! In the future, I'll try to format the reports properly with the markup codes..
