NettetTrait core :: panic :: UnwindSafe. A marker trait which represents “panic safe” types in Rust. This trait is implemented by default for many types and behaves similarly in terms of inference of implementation to the Send and Sync traits. The purpose of this trait is to encode what types are safe to cross a catch_unwind boundary with no fear ...

Nettet7. okt. 2024 · @Fureeish ARM, and especially NEON. I won't argue about x68 since I fortunately don't have to deal with it. Neon intrinsic has been around for over ten years, and GCC is still unusable. That's a fact. People should be aware of that. PS: I don't see any x86 tag here. – Nettet二、NEON 数据类型和指令类型 2.1、NEON 数据类型. NEON 向量数据类型是根据以下模式命名的：x_t，eg：int8x16_t 是一个16 通道的向量，每个通道包含一个有符号 8 位整数; NEON 还提供了数组向量数据类型，命名模式如下：xx_t，eg：int8x16x4_t 是一个 ... finny lopez

The simplest is to use derive: struct MyStruct; impl Copy for MyStruct { } impl Clone for MyStruct { fn clone (&self) -> MyStruct { *self } } There is a small difference between the two: the derive strategy will also place a Copy bound on type parameters, which isn’t always desired.
