Struct NodeId 

pub struct NodeId(/* private fields */);

Stable source identity shared by registration, diagnostics, and pruning. 注册、诊断和修剪共用的稳定源码身份。

This is a compact 128-bit prefix of SHA-256 for indexing and diagnostics, not a cryptographic signature. Plugin trust must use the full digest and a signature verifier. 这是用于索引和诊断的 SHA-256 128 位短标识，不是密码学签名。插件信任必须 使用完整摘要和签名验证器。

Implementations

impl NodeId

pub const fn from_path(relative_path: &str, declared_name: &str) -> NodeId

Hash relative_path + 0x00 + declared_name during constant evaluation. 在常量求值期间散列“相对路径 + 0x00 + 声明名”。

Both slices are separator-folded here; from_namespaced_path explains why the namespaced entry point folds only its first two components. 这里两个切片都会折叠分隔符；命名空间入口为何只折叠前两个组成部分，见 from_namespaced_path。

pub const fn from_namespaced_path( namespace: &str, relative_path: &str, declared_name: &str, ) -> NodeId

Hash a declaration together with the package namespace that owns it. 将声明与拥有它的包命名空间一起散列，避免不同库的相对路径串库。

pub const fn from_bytes(input: &[u8]) -> NodeId

Hash one byte slice; primarily useful for standard-vector tests. 散列单个字节切片，主要用于标准向量测试。

pub const fn into_bytes(self) -> [u8; 16]

The raw 128-bit identity, round-trippable through from_raw at build time. 原始 128 位身份，构建期可经 from_raw 还原。

pub const fn pruning_table(self) -> [u64; 4096]

Produce a node-specific compile-time payload for pruning verification. 为修剪验证生成节点专属的编译期负载。

The table is emitted only when the owning node’s probe is reached. 只有触达所属节点探针时，这张表才会进入最终产物。
