Missing auto completion on std library

[chojs23]

rust-analyzer version : 2023-11-06

When I didn't import std::io::Write trait for TcpStream struct and I expect write() method for suggestion, but rust-analyzer only shows four methods.

If I add use::std::Write , It shows write() method for suggestions.

I use neovim and lsp-config and when I use vscode and rust-analyzer plugin, It does not work like neovim.

With intellij and jetbrain's rust plugin, It shows many other method for struct.

Confirmed, this one is pretty annoying. It's interesting that we do offer suggestions for write_fmt and write_all, from the same trait.

@lnicola So this behavior is intended cause rust-analyzer didn't implement this ? I thought i have some wrong settings on neovim.

It's caused by RA, not NeoVim, but probably not intended.

I use neovim and lsp-config and when I use vscode and rust-analyzer plugin, It does not work like neovim.

Do you mean you get the write completion in VS Code?

@lnicola Both stable and nightly version of VScode rust analyzer extension gives me same suggestions as neovim (Not showing write())

it's same for me.

Any update on this?

No updates here yet, can try looking into this next week. Interestingly though, this works fine for Vec<u8>, so there is something special going on with TcpStream here
