Async Lightweight HTTP Client (aka ALHC)

What if we need async but also lightweight http client without using such a large library like reqwest, isahc or surf?

ALHC is a async http client library that using System library to reduce binary size and provide async request feature.

Our little request example https with release build can be 182 KB, which is smaller than tinyget's http example. If we use rustc nightly feature plus build-std and panic_immediate_abort, it'll be incredibly 60 KB!

Currently work in progress and only support Windows (Using WinHTTP) and macOS in progress (Using CFNetwork), linux are planned.

Compilation binary size comparison

Note: the size optimization argument is: cargo +nightly run --release -Z build-std=core,alloc,std,panic_abort -Z build-std-features=panic_immediate_abort --target [TARGET] --example [EXAMPLE] and some configuration in Cargo.toml
