Simulation-First

Tests are written BEFORE implementation. SimStorageBackend enables deterministic testing with fault injection.

Structs

Entity

An entity in archival memory.

EntityBuilder

Builder for Entity with fluent API.

EvolutionRelation

A relationship between two memories showing how one evolved from another.

EvolutionRelationBuilder

Builder for EvolutionRelation with fluent API.

SimStorageBackend

In-memory storage backend for testing.

SimVectorBackend

In-memory vector backend for deterministic simulation testing.

SourceRef

Reference to source content (URL, file path, S3 URI, etc.)

VectorSearchResult

Result of a similarity search.

Enums

EntityType

Types of entities in archival memory.

EvolutionType

Types of evolution relationships between memories.

StorageError

Errors from storage operations.

Traits

StorageBackend

Abstract storage backend for entities.

VectorBackend

Trait for vector embedding storage backends.

Type Aliases

StorageResult

Result type for storage operations.
