Libusb Rust 绑定

libusb-src 包提供对 libusb C库的声明和链接。

libusb版本：1.0.26

在ubuntu和windows上测试过

示例

use libusb_src as ffi;

fn main(){
    unsafe {
        let mut context = std::mem::MaybeUninit::<*mut ffi::libusb_context>::uninit();
        match ffi::libusb_init(context.as_mut_ptr()){
            0 => (),
            err => panic!("Failed to init libusb {}", err),
        }
        let mut list = std::mem::MaybeUninit::<*const *mut ffi::libusb_device>::uninit();
        let list_size = ffi::libusb_get_device_list(context.assume_init(), list.as_mut_ptr());
        if list_size < 0  {
            panic!("Failed to get device list {} {:p}", -list_size, list.assume_init());
        }else { 
            println!("Usb device count: {}", list_size);
        }
        ffi::libusb_free_device_list(list.assume_init(), 1);
        ffi::libusb_exit(context.assume_init());
    }
}
