Struct MmapReader 

pub struct MmapReader { /* private fields */ }

Read-only memory-mapped access to an .amem file.

Implementations

impl MmapReader

pub fn open(path: &Path) -> AmemResult<Self>

Open an .amem file for memory-mapped read access.

pub fn header(&self) -> &FileHeader

Get the file header.

pub fn read_node(&self, id: u64) -> AmemResult<CognitiveEvent>

Read a single node record by ID (O(1) access).

pub fn read_content(&self, id: u64) -> AmemResult<String>

Read a node’s content (decompress from content block).

pub fn read_feature_vec(&self, id: u64) -> AmemResult<Vec<f32>>

Read a node’s feature vector.

pub fn read_edges(&self, id: u64) -> AmemResult<Vec<Edge>>

Read all edges from a node.

pub fn read_full_graph(&self) -> AmemResult<MemoryGraph>

Read the full graph into memory.

pub fn similarity_to(&self, id: u64, query: &[f32]) -> AmemResult<f32>

Compute cosine similarity between a query and a node’s feature vector.

pub fn batch_similarity( &self, query: &[f32], top_k: usize, min_similarity: f32, ) -> AmemResult<Vec<SimilarityMatch>>

Batch similarity: scan all feature vectors and return top-k matches.
