## Summary The priority latency-sensitive is reserved for actions that need to run immediately because they would otherwise block the user's action. An example of this is a format request. VS code blocks the editor until the save action is complete. That's why formatting a document is very sensitive to delays and it's important that we always have a worker thread available to run a format request *immediately*. Another example are code completions, where it's important that they appear immediately when the user types. On the other hand, showing diagnostics, hover, or inlay hints has high priority but users are used that the editor takes a few ms to compute the overlay. Computing this information can also be expensive (e.g. find all references), blocking the worker for quiet some time (a few 100ms). That's why it's important that those requests don't clog the sensitive worker threads. |

The Ruff Language Server
ruff server is a language server that powers Ruff's editor integrations.
The job of the language server is to listen for requests from the client (in this case, the code editor of your choice) and call into Ruff's linter and formatter crates to construct real-time diagnostics or formatted code, which is then sent back to the client. It also tracks configuration files in your editor's workspace, and will refresh its in-memory configuration whenever those files are modified.
Refer to the documentation for more information on how to set up the language server with your editor and configure it to your liking.
