Here is a short list with some of the changes: - don't suggest the same thing that is the current token - suggest removing the current token if the following token is one of the suggestions (maybe incorrect) - tell the user to put a type or lifetime after where if there is none (as a warning) - reduce the amount of tokens suggested (via the new eat_noexpect and check_noexpect methods) If any of these changes are undesirable, i can remove them, thanks! remove unnecessary `to_string` and `String::new` 2022-06-13T06:48:40+00:00 Takayuki Maeda takoyaki0316@gmail.com 2022-06-13T06:48:40+00:00 urn:sha1:77d6176e69de8bcdc15a12402ce7245f06ca2329 Improves parser diagnostics, fixes #93867 2022-06-12T15:48:52+00:00 threadexception hannes.gaumann@outlook.de 2022-05-01T17:05:35+00:00 urn:sha1:21fdd549f63499a6f15160c22175cc9c3bbeb473 rustc_ast: Harmonize delimiter naming with `proc_macro::Delimiter` 2022-04-28T07:04:29+00:00 Vadim Petrochenkov vadim.petrochenkov@gmail.com 2022-04-26T12:40:14+00:00 urn:sha1:2733ec1be34b1ae9f22c70c901bb89229adf9def better error for binder on associated type bound 2022-04-10T23:41:15+00:00 Michael Goulet michael@errs.io 2022-04-07T06:08:22+00:00 urn:sha1:b65265b5e1c70d8c1685efc3a899ce3d89362ad7 Shrink `Nonterminal`. 2022-04-07T02:51:50+00:00 Nicholas Nethercote n.nethercote@gmail.com 2022-04-06T02:08:39+00:00 urn:sha1:d9592c2d9f0db851b090c10c0cc3560b87fc7789 By heap allocating the argument within `NtPath`, `NtVis`, and `NtStmt`.
