Trait NamedDigest 

pub trait NamedDigest {
    type Core: Digest;
}

哈希器与底层摘要之间的桥：声明 Core 即由 blanket impl 获得 Hasher。

Core 走 RustCrypto digest 0.10 代际：sha2 / sha3 / blake2 / streebog / belt-hash 转出的是同一个 Digest trait，故一个 blanket 覆盖全部（bound 写作 sha2::Digest 只是取路径，本 crate 未直接依赖 digest）。SM3（sm3 crate 属 digest 0.11 代际）与 BLAKE3（独立实现，不走 digest trait）不适用， 二者各自实现 Hasher。

Required Associated Types

type Core: Digest

提供摘要的底层实现。

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
