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.

HTTPS Example:

```rust use alhc::prelude::; use alhc::;

use pollster::FutureExt;

fn main() -> DynResult { let client = getclientbuilder().build().unwrap();

let r = client
    .post("https://httpbin.org/anything")?
    .header("user-agent", "alhc/0.2.0")
    .body_string("Hello World!".repeat(20))
    .block_on()?
    .recv_string()
    .block_on()?;

println!("{r}");

Ok(())

} ```

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 being planned.

Platform Status

| Name | Status | Note | | ------- | ----------------- | ------------------------------------------------ | | Windows | Working | | | MacOS | Working | Maybe failed sometime or very slow (To be fixed) | | Linux | Under Development | |

Features

• async_t_boxed: Use async-trait instead of async-t, which requires nightly rustc but with zero-cost. Default is enabled.
• ~~serde: Can give you the ability of send/receive json data without manually call serde_json. Default is disabled.~~

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
