Struct Node 

pub struct Node {
    pub path: Vec<String>,
    pub content: BTreeMap<String, BTreeSet<String>>,
    pub labels: BTreeMap<String, String>,
    pub refs: Vec<Ref>,
}

A node of the tree: identity (path) + content (attributes). The collector fills it; this crate computes the hashes (SPEC §4.2, §5).

Fields

path: Vec<String>

The node’s identity: its ordered location in the tree. Unique within a snapshot.

content: BTreeMap<String, BTreeSet<String>>

Attributes: each name maps to a set of string values (a scalar is a one-element set).

labels: BTreeMap<String, String>

Free-form annotation for grouping. Never hashed, never diffed.

refs: Vec<Ref>

Directed annotation edges to other nodes. Never hashed, never diffed.

Implementations

impl Node

pub fn identity_key(&self) -> Result<String, Error>

identity_key = SHA-256 of the canonical path (“which node this is”).

Validates the node first — an implementation MUST NOT hash ill-formed input (SPEC §9), so an ill-formed node yields an error, never a hash.

pub fn content_hash(&self) -> Result<String, Error>

content_hash = SHA-256 of the canonical content (“what the node is”).

Validates the node first — an implementation MUST NOT hash ill-formed input (SPEC §9), so an ill-formed node yields an error, never a hash.

pub fn canonical_path(&self) -> String

The exact canonical bytes hashed for the identity (for inspection/debugging). Not validated — these are bytes, not a hash; use Node::identity_key to hash.

pub fn canonical_content(&self) -> String

The exact canonical bytes hashed for the content (for inspection/debugging). Not validated — these are bytes, not a hash; use Node::content_hash to hash.
