Struct TensorProvenanceTracker 

pub struct TensorProvenanceTracker {
    pub records: HashMap<u64, ProvenanceRecord>,
    pub tensor_records: HashMap<u64, Vec<u64>>,
    pub next_record_id: u64,
}

Tracks the full provenance of tensor values and inference results.

Records are keyed by a globally unique record_id and can also be looked up by tensor_id (returning all records for that tensor in insertion order).

Fields

records: HashMap<u64, ProvenanceRecord>

All records, keyed by record_id.

tensor_records: HashMap<u64, Vec<u64>>

Maps each tensor_id to the ordered list of record_ids for that tensor.

next_record_id: u64

Monotonically increasing counter used to assign record IDs.

Implementations

impl TensorProvenanceTracker

pub fn new() -> Self

Creates a new, empty tracker.

pub fn record( &mut self, tensor_id: u64, kind: ProvenanceKind, confidence: f64, tick: u64, ) -> u64

Records a new provenance entry for tensor_id.

Returns the newly assigned record_id.

pub fn chain_for(&self, tensor_id: u64) -> ProvenanceChain

Returns the ProvenanceChain for tensor_id in insertion order.

Returns an empty chain when tensor_id is not known.

pub fn get_record(&self, record_id: u64) -> Option<&ProvenanceRecord>

Returns a reference to the record with the given record_id, or None.

pub fn records_for_tensor(&self, tensor_id: u64) -> Vec<&ProvenanceRecord>

Returns all records for tensor_id in insertion order.

pub fn externally_sourced_tensors(&self) -> Vec<u64>

Returns a sorted list of tensor IDs for which at least one record is externally sourced (i.e., ProvenanceRecord::is_externally_sourced returns true).

pub fn delete_tensor(&mut self, tensor_id: u64) -> bool

Removes all records associated with tensor_id.

Returns true on success, false if tensor_id was not found.

pub fn stats(&self) -> ProvenanceStats

Returns aggregate statistics across all stored records.

Trait Implementations

impl Debug for TensorProvenanceTracker

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

Formats the value using the given formatter.

impl Default for TensorProvenanceTracker

fn default() -> TensorProvenanceTracker

Returns the “default value” for a type.
