From 420dd187e1572bb7e232781bc4377a80c8eb64fb Mon Sep 17 00:00:00 2001 From: Manos Pitsidianakis Date: Thu, 21 May 2026 13:21:15 +0300 Subject: [PATCH] .gitignore: ignore rustc long type txt files When rustc prints an error containing a long type that doesn't fit in a line, it will write the whole thing in a .txt file and print messages like: note: the full type name has been written to 'path/to/subsystem/module_name.long-type-11621316855315349594.txt' [ Depending on the compiler version and the kind of error, there are two possible spellings -- copying them here for reference: = note: the full name for the type has been written to '...long-type-...txt' = note: the full type name has been written to '...long-type-...txt' In addition, we could clean the files as well in one of our cleaning Make targets [1][2]. Another option would be `--verbose` (but it implies more things that we probably don't want) or `-Zwrite-long-types-to-disk=no` (unstable so far, but a possible alternative if we prefer to avoid the files and simply see the long types in the output -- I asked upstream Rust about it [3]).
