Guess content type from path
Hello, I'm looking to serve data from R2 via workers. I'm used to Rust, and have used https://docs.rs/mime_guess/latest/mime_guess/ in the past to "guess" the mime type for a piece of content based on the path given.
What's the easiest way to do this with workers?
mime_guess - Rust
Guessing of MIME types by file extension.

Ideally the type would be stored with the object in R2 as httpMetadata so you can retrieve it - otherwise I guess a mime DB (like that) is the only way
mime_guess 
yeah - what kian said. There is a library that works with Workers I've used, but ideally on upload you set the proper content type and then it stores it alongside the object in the metadata
