Hey there folks, I hope you're all doing well. This issue is related to sublimelsp/LSP-rust-analyzer#80

In editors such as Sublime Text, inlay hints do not show up until an edit is made to a document. As Rafał has mentioned:

Server initially responds with an error to textDocument/inlayHint requests as it's still initializing.

Since in the new spec version there exists a workspace/inlayHint/refresh notification (and we support it), it would be most natural if the server would send it once it finishes loading.

Please see related documentation for workspace/inlayHint/refresh here.

Would you please consider supporting this? 😄

Thanks in advance!

Hmm, we should already be sending a refresh notification once we have finished loading.

I can confirm that rust-analyzer sends /refresh requests after the corresponding client capability is set, smth. like

lsp_types::ClientCapabilities {
    workspace: Some(lsp_types::WorkspaceClientCapabilities {
        inlay_hint: Some(lsp_types::InlayHintWorkspaceClientCapabilities {
            refresh_support: Some(true),
        }),
        // ... snip
    }),
// ... snip
}

rust-analyzer then sends multiple calls on server startup, and on every change to a file.

I do not quite understand this behavior, honestly: any editors knows beforehand about the change to a file, then communicates the change to the language server and gets back the /refresh request from r-a.
Also, neither editor can know if a server will send any /refresh request at all, the only way to communicate with server about /refresh is described above, in the client capabilities.
Last but not least, /refresh request is global, forcing the editor to invalidate all hints.

Modulo files in the same language server, any change to a file forces the editor to invalidate all opened files' hints — later /refresh does not bring any new information.
After the change, editor propagates the changes to the language server, and either has to wait for /refresh with some timeout, introducing latencies, or do two inlayHint requests in a row for the same state.

Neither makes sense to me, what do I miss?

Ye, maybe the refreshes we do on file changes aren't needed at all. The spec isn't really clear on that as usual

I'm running into this too. It looks like rust-analyzer does send a workspace/inlayHint/refresh event once the server becomes quiescent, which happens after the workspace is loaded but before indexing. But inlay hints such as type information are not available before indexing has completed.

In this log, rust-analyzer refreshes semantic tokens and inlay hints after the "Roots Scanned" and "Fetching" progress reports, but before "Indexing" begins. My client responds to this event by requesting inlay hints, rust-analyzer responds with nil, and does not send another workspace/inlayHint/refresh event until the document is edited.

Do not send inlay hint refresh requests on file edits

See #13369 (comment)

Editor itself is able to invalidate hints after edits, and /refresh was sent after editor reports changes to the language server. This forces the editor to either query & invalidate the hints twice after every edit, or wait for /refresh to come before querying the hints.

Both options are rather useless, so instead, send a request on server startup only: client editors do not know when the server actually starts up, this will help to query the initial hints after editor was open and the server was still starting up.

which means rust-analyzer does send a workspace/inlayHint/refresh request, and does that quite late now.

Unfortunately, I still see no hints in VSCode, and neither does it send the textDocument/inlayHint afterwards.
The spec says that delays can be done only if the document is not visible (which is not true):

Note that the client still has the freedom to delay the re-calculation of the inlay hints if for example an editor is currently not visible.

It feels like a bug in VSCode, not in rust-analyzer.
Or, at least, not with /refresh request sending, so I think nothing else can be done for this issue here?
I have also checked it in the editor I work on and it does receive the hint data after that single workspace/inlayHint/refresh request from the server, so VSCode could do that in theory.

an editor is currently not visible.

I think with not visible they mean not focused (as in not rendering) but still open.

It might be a VSCode bug, given they are handling inlay hints in an odd way in general. It waits a second or so with asking for inlay hints after you stopped typing(which is incredibly annoying), so it might just not query for them if the refresh doesn't make it in a certain time interval.
