我有一个存储在obj
中的存储结构(Arc<Mutex>
)。 Mutex
是Parking_lot板条箱中std::sync::Mutex
的改进版本。我需要反序列化包装的对象(obj
),但是,我得到一个错误:
the trait `_IMPL_DESERIALIZE_FOR_SecurityLevel::_serde::Deserialize<'_>` is not implemented for `lock_api::mutex::Mutex<parking_lot::raw_mutex::RawMutex, Obj>`
在我的Cargo.toml中,我有(尤其是):
serde = { version = "1.0.89", features = ["rc"] }
parking_lot = {version = "0.8", features = ["nightly"]}
我应该怎么做?有解决方法,还是我必须手动实现这些特征?
答案 0 :(得分:3)
对Serde的支持已添加到serde
feature flag下的parking_lot 0.8:
parking_lot = { version = "0.8", features = ["nightly", "serde"] }
使用此代码,您提供的代码将被编译。这也可以编译:
use parking_lot::Mutex;
use serde::{Deserialize, Serialize};
fn implements<T>()
where
Mutex<T>: for<'a> Deserialize<'a> + Serialize,
{
}
