> I can't rewrite the world, an async runtime and web server are just too difficult and take to long for me to justify writing for a project like this (although I should eventually just for a better understanding).

I did this and it only solved half of the bloat:

https://crates.io/crates/safina - Safe async runtime, 6k lines

https://crates.io/crates/servlin - Modular HTTP server library, threaded handlers and async performance, 8k lines.

I use safina+servlin and 1,000 lines of Rust to run https://www.applin.dev, on a cheap VM. It serves some static files, a simple form, receives Stripe webooks, and talks to Postgres and Postmark. It depends on some heavy crate trees: async-fs, async-net, chrono, diesel, rand (libc), serde_json, ureq, and url.

2,088,283 lines of Rust are downloaded by `cargo vendor` run in the project dir.

986,513 lines using https://github.com/coreos/cargo-vendor-filterer to try to download only Linux deps with `cargo vendor-filterer --platform=x86_64-unknown-linux-gnu`. This still downloads the `winapi` crate and other Windows crates, but they contain only 22k lines.

976,338 lines omitting development dependencies with `cargo vendor-filterer --platform=x86_64-unknown-linux-gnu --keep-dep-kinds=normal`.

754,368 lines excluding tests with `cargo vendor-filterer --platform=aarch64-apple-darwin --exclude-crate-path='*#tests' deps.filtered`.

750k lines is a lot to support a 1k-line project. I guess I could remove the heavy deps with another 200 hours of work, and might end up with some lean crates. I've been waiting for someone to write a good threaded Rust Postgres client.
