Struct MemoryConfig 

pub struct MemoryConfig {
    pub core_memory_bytes: usize,
    pub working_memory_bytes: usize,
    pub working_memory_ttl: Duration,
    pub generate_embeddings: bool,
    pub embedding_batch_size: usize,
    pub default_recall_limit: usize,
    pub semantic_search_enabled: bool,
    pub query_expansion_enabled: bool,
}

Global configuration for Memory system.

TigerStyle:

• Sensible defaults via Default impl
• Builder pattern for customization
• All fields public for transparency

Example

use umi_memory::umi::MemoryConfig;

let config = MemoryConfig::default()
    .with_recall_limit(20)
    .without_embeddings();

Fields

core_memory_bytes: usize

Core memory size in bytes (always in LLM context).

Default: 32KB

working_memory_bytes: usize

Working memory size in bytes (session state with TTL).

Default: 1MB

working_memory_ttl: Duration

Working memory time-to-live duration.

Default: 1 hour

generate_embeddings: bool

Whether to generate embeddings for entities.

Default: true

embedding_batch_size: usize

Embedding batch size for bulk operations.

Default: 100

default_recall_limit: usize

Default recall result limit.

Default: 10

semantic_search_enabled: bool

Whether to enable semantic (vector) search.

Default: true

query_expansion_enabled: bool

Whether to enable LLM query expansion for retrieval.

Default: true (auto-enabled when beneficial)
