Enum MemoryRoute 

pub enum MemoryRoute {
    Keyword,
    Semantic,
    Hybrid,
    Graph,
    Episodic,
}

Classification of which memory backend(s) to query.

Variants

Keyword

Full-text search only (SQLite FTS5). Fast, good for keyword/exact queries.

Semantic

Vector search only (Qdrant). Good for semantic/conceptual queries.

Hybrid

Both backends, results merged by reciprocal rank fusion.

Graph

Graph-based retrieval via BFS traversal. Good for relationship queries. When the graph-memory feature is disabled, callers treat this as Hybrid.

Episodic

FTS5 search with a timestamp-range filter. Used for temporal/episodic queries (“what did we discuss yesterday”, “last week’s conversation about Rust”).

Known trade-off (MVP): skips vector search entirely for speed. Semantically similar but lexically different messages may be missed. Use Hybrid route when semantic precision matters more than temporal filtering.

Trait Implementations

impl Clone for MemoryRoute

fn clone(&self) -> MemoryRoute

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryRoute

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

Formats the value using the given formatter.

impl PartialEq for MemoryRoute

fn eq(&self, other: &MemoryRoute) -> 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.
