Struct CognitiveDiff 

pub struct CognitiveDiff {
    pub added_docs: Vec<Document>,
    pub removed_doc_ids: Vec<Uuid>,
    pub added_chunks: Vec<Chunk>,
    pub removed_chunk_ids: Vec<Uuid>,
    pub added_embeddings: Vec<Embedding>,
    pub removed_embedding_ids: Vec<Uuid>,
    pub added_edges: Vec<Edge>,
    pub removed_edges: Vec<(Uuid, Uuid, EdgeKind)>,
    pub metadata: DiffMetadata,
}

A cognitive diff containing all changes between two state roots.

Per CP-001 §2.7: devices exchange diffs rather than full state to minimize bandwidth and computation.

Note: there is no updated_docs — updates are modeled as remove + add (per spec pattern).

Fields

added_docs: Vec<Document>

Documents added in this diff

removed_doc_ids: Vec<Uuid>

IDs of documents removed

added_chunks: Vec<Chunk>

Chunks added

removed_chunk_ids: Vec<Uuid>

IDs of chunks removed

added_embeddings: Vec<Embedding>

Embeddings added

removed_embedding_ids: Vec<Uuid>

IDs of embeddings removed

added_edges: Vec<Edge>

Edges added

removed_edges: Vec<(Uuid, Uuid, EdgeKind)>

Edges removed — identified by (source, target, kind) triple

metadata: DiffMetadata

Diff metadata

Implementations

impl CognitiveDiff

pub fn empty(prev_root: [u8; 32], device_id: Uuid, seq: u64, hlc: Hlc) -> Self

Create an empty diff (no changes)

pub fn is_empty(&self) -> bool

Check if the diff is empty (no changes)

pub fn change_count(&self) -> usize

Count total number of changes in this diff

pub fn estimated_size(&self) -> usize

Estimate serialized size in bytes

Trait Implementations

impl Clone for CognitiveDiff

fn clone(&self) -> CognitiveDiff

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CognitiveDiff

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CognitiveDiff

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CognitiveDiff

fn eq(&self, other: &Self) -> 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 CognitiveDiff

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
