rustlang: datatype helper?

[Kreyren]

Apparently jetbrains products have a helper that outputs datatypes of rustlang in the editor:

Is there a way to get this in gitpod? I believe that it would help a lot with a development especially for new developers to understand the language better.

Relevant plugin: https://plugins.jetbrains.com/plugin/8182-rust

Relevant rust-lang/vscode-rust#374

[svenefftinge]

It should be implemented in the rust vs code extension.

[Kreyren]

@svenefftinge can't confirm on my end

[Kreyren]

PSA As referrenced on rust-lang/vscode-rust#374 (comment) this is apparently implemented in rust-analyzer extension (https://github.com/rust-analyzer/rust-analyzer) which requires compilation to be imported on the vscode which results in following on gitpod:

Setting executable code that returns exit 0 fixes the issue on vscode-rls

[Kreyren]

FWIW the rust-analyzer also fails with what i assume is interference from built-in extension

[Kreyren]

FWIW: Rust analyzer is now available as official vscode extension

Tried to implement it with required datatype helper on https://github.com/RXT0112/Zernit/tree/6ceaff2979918b85654a9397072b8e97408cdab6

which results in:

[Error - 9:46:02 PM] Notify file events failed.

I assume this being theia bug?

[Kreyren]

ping @JesterOrNot Can you take a look at this and approve for transfer if this is a theia bug so that i am not flooding their bug tracker with something that might be a gitpod bug? ^-^

[svenefftinge]

Yes, seems like we need to implement that API in Theia. Could you open a ticket there?

[llebout]

eclipse-theia/theia#6623 was solved.
Another API missing: eclipse-theia/theia#7608

[Kreyren]

It seems to be implemented now ^-^

Assuming solved
