This error occurs with rustc >= 1.82, but succeeds with version 1.81. can add rust-toolchain.toml?

For NixOS users who use nixos-unstable branch, you might need to use rust-overlay since current nixpkgs version is 1.82.0.

module.nix

{ inputs, ... }:
{
  nixpkgs.overlays = [
    inputs.rust-overlay.overlays.default

    (final: prev: {
      kime = prev.callPackage ./package.nix {
        inherit (final) rust-bin;
      };
    })
  ];
}

Are there any ways to fix it?

Seems like this is caused by rust-lang/rust#128370

[honnip]

here is a simple overlay for NixOS:

final: prev:
  let
    rustChannel = inputs.rust-overlay.packages.x86_64-linux.rust_1_81_0;
  in
  {
    kime = prev.kime.override {
      rustPlatform = prev.makeRustPlatform {
        rustc = rustChannel;
        cargo = rustChannel;
      };
      rustc = rustChannel;
      cargo = rustChannel;
    };
  };

I doubt it since the PR has already been merged into 1.82.0. Please also see https://github.com/Riey/kime/issues/693#issuecomment-2612017513 .
