#[xxfunc::main] macro

user code should be in src/main.rs

#![no_main]

#[xxfunc::main]
fn main(data: &[u8]) {
    println!("Hello, world!, data length: {}", data.len());
}

it will expand into

#![feature(prelude_import)]
#![no_main]
#[prelude_import]
use std::prelude::rust_2021::*;
#[macro_use]
extern crate std;
use core::slice;

#[no_mangle]
pub extern "C" fn alloc(size: usize) -> *mut u8 {
    unsafe {
        GLOBAL_BUFFER.clear();
        GLOBAL_BUFFER.reserve(size);
        GLOBAL_BUFFER.as_mut_ptr()
    }
}
#[no_mangle]
pub extern "C" fn process(size: usize) {
    let data = unsafe { &GLOBAL_BUFFER[..size] };
    __xxfunc_inner(data);
