克里皮对静态声明说“太多的争论”

Question

这段代码来自我的操作系统。

#[global_allocator]
pub static ALLOCATOR: LockedHeap = LockedHeap::empty();

克里皮说，这个函数有太多的参数。

error: this function has too many arguments (4/3)
  --> src/mem/allocator/heap.rs:14:1
   |
14 | pub static ALLOCATOR: LockedHeap = LockedHeap::empty();
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   |
note: the lint level is defined here
  --> src/lib.rs:14:9
   |
14 | #![deny(clippy::all)]
   |         ^^^^^^^^^^^
   = note: `#[deny(clippy::too_many_arguments)]` implied by `#[deny(clippy::all)]`
   = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#too_many_arguments
   = note: this error originates in an attribute macro (in Nightly builds, run with -Z macro-backtrace for more info)

我认为原因是global_allocator属性或linked_list_allocator机箱，所以我使用它们编写了最低限度的代码。

#![deny(clippy::all)]
#![feature(alloc_error_handler)]
#![feature(start)]
#![feature(lang_items)]
#![no_std]

#[global_allocator]
pub static LIST: linked_list_allocator::LockedHeap = linked_list_allocator::LockedHeap::empty();

#[start]
fn _start(c: isize, v: *const *const u8) -> isize {
    3
}

#[alloc_error_handler]
fn oom(_layout: core::alloc::Layout) -> ! {
    panic!()
}

#[panic_handler]
fn panic(_info: &core::panic::PanicInfo) -> ! {
    loop {}
}

#[lang = "eh_personality"]
fn eh() {}

然而，克里皮对此代码只字未提。

为什么克里皮抱怨第一段代码？

Answer 1

如果克利皮在正常函数声明中抱怨这一点，请使用上述函数上的#[allow(clippy::too_many_arguments)]属性来消除错误。
