Async preview using skim as a library

[rcorre]

Hi, I'm using skim as a library. Is there a way to use an async function (e.g. an HTTP request) as a preview function? Ideally skim would start the function, then show the result in the preview when it completes, or cancel it if a new item is selected before it completes.

Hi, you should be able to do it using the preview_fn, by wrapping your async code into a synchronous closure. This will probably induce an overhead, to start the async runtime, but otherwise it should work without issues.
