如何解决如何修复未为 `Hash` 实现的特性 `parity_scale_codec::codec::WrapperTypeEncode`

我正在尝试定义 Substrate 运行时 API。我正在使用基板主分支作为依赖项。

在构建代码时，我收到以下错误：

#![cfg_attr(not(feature = "std"),no_std)]
use codec::Codec;
use codec::{Encode,Decode};


sp_api::decl_runtime_apis! {
/// The API to verify barcode
pub trait BarcodeScannerApi<Hash> where
    Hash: Codec,{
    /// Verify barcode
    fn is_valid_barcode(barcode: Hash) -> bool;
}
}

请帮我解决这个问题。
