I have the feelings that it happens often while typing ;

use crate::error::Result;

lnicola · 2020-09-11T12:52:08Z

Which Rust toolchain are you using?

0x8f701 · 2020-09-11T12:52:50Z

@lnicola nightly

lnicola · 2020-09-11T12:53:32Z

#5651 / #5773, although the error message seems different.

0x8f701 · 2020-09-11T12:55:35Z

@lnicola it reminds me of #5864, because when this error happens, it shows also something error messages like [SEMICON]....

lnicola · 2020-09-11T18:29:37Z

Can you try with #5651?

lnicola · 2020-10-16T06:11:38Z

@GopherJ I think this was fixed, are you still seeing it?

Cooie · 2020-11-30T12:51:16Z

I have a similar issue with neovim + coc.nvim + coc-rust-analyzer

Neovim is not responding for about 1s every time when I choose/type directly unwrap() or unwrap_err().

FYI:
rust-analyzer: 2020-11-30
neovim: 0.4.4
coc.nvim: 0.0.79
coc-rust-analyzer: 0.18.0
OS: macOS 11.0.1
iTerm2: Build 3.4.2beta3

bjorn3 · 2020-11-30T12:56:37Z

Does the server log show a panic? If not, this is a separate issue.

Cooie · 2020-12-01T03:56:13Z

No, there is no panic log from the server log.

flodiebold · 2020-12-21T20:23:42Z

@GopherJ are you still encountering this?

0x8f701 · 2020-12-22T10:22:47Z

@flodiebold indeed I didn't see it anymore, is there any action behind this? if yes I think it can be closed

flodiebold · 2020-12-22T10:45:24Z

Maybe #5651, but there were also lots of other changes to the proc macro code.

flodiebold added the S-unactionable label Dec 21, 2020

flodiebold closed this as completed Dec 22, 2020
