Struct ArchitectureFingerprint 

pub struct ArchitectureFingerprint {
    pub digest: String,
    pub nodes: BTreeMap<String, String>,
    pub edges: Vec<EdgeRef>,
    pub n_nodes: usize,
    pub n_edges: usize,
    pub node_config: BTreeMap<String, String>,
}

Structural identity of a graph, exact and fuzzy.

Written to fingerprint.json in every tracked run directory and copied into the ExperimentRecord so the pool can rank past work by architectural resemblance without re-reading any graph.

Fields

digest: String

Hex SHA-256 of the canonical form — exact, id-sensitive.

nodes: BTreeMap<String, String>

Node id → type token, in id order. Keeping the ids is what lets two fingerprints be diffed (which node was swapped) and not only compared; the token bags below deliberately drop them.

edges: Vec<EdgeRef>

Every edge as (source id, target id, kind), sorted.

n_nodes: usize

Node count — cheap size signal for ranking without opening nodes.

n_edges: usize

Edge count — same role as n_nodes.

node_config: BTreeMap<String, String>

Per-node filter config hash, keyed by node id. Empty unless the caller had a filter registry to hand (soma-core has no access to filter instances; the Python binding fills this in at run start).

Implementations

impl ArchitectureFingerprint

pub fn of(graph: &Graph) -> Result<Self>

Fingerprint graph. Errors only if the canonical form is not serializable, which for a Graph means a bug, not bad input.

pub fn with_node_config(self, node_config: BTreeMap<String, String>) -> Self

Attach per-node config hashes (node id → hex hash).

pub fn short(&self) -> &str

Short prefix of the digest, for display.

pub fn node_tokens(&self) -> Vec<String>

One type token per node, sorted, duplicates kept (two scalers are structurally different from one). Carries no node ids, so it survives renaming — the fuzzy half of the fingerprint.

pub fn edge_tokens(&self) -> Vec<String>

One sourceToken>targetToken token per edge (~> for control edges), sorted, duplicates kept. Also id-free.

Trait Implementations

impl Clone for ArchitectureFingerprint

fn clone(&self) -> ArchitectureFingerprint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ArchitectureFingerprint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ArchitectureFingerprint

fn default() -> ArchitectureFingerprint

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ArchitectureFingerprint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ArchitectureFingerprint

fn eq(&self, other: &ArchitectureFingerprint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ArchitectureFingerprint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
