A single memory item

Fields

id: String

Unique identifier

content: String

Memory content

timestamp: DateTime<Utc>

When this memory was created

importance: f32

Importance score (0.0 - 1.0)

tags: Vec<String>

Tags for categorization

memory_type: MemoryType

Memory type

metadata: HashMap<String, String>

Associated metadata

access_count: u32

Number of times this memory was accessed

last_accessed: Option<DateTime<Utc>>

Last access time

content_lower: String

Cached lowercase content for fast substring search

Implementations

impl MemoryItem

pub fn new(content: impl Into<String>) -> Self

Create a new memory item

pub fn with_importance(self, importance: f32) -> Self

Set importance

pub fn with_tags(self, tags: Vec<String>) -> Self

Add tags

pub fn with_tag(self, tag: impl Into<String>) -> Self

Add a single tag

pub fn with_type(self, memory_type: MemoryType) -> Self

Set memory type

pub fn with_metadata( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

Add metadata

pub fn record_access(&mut self)

Record access

pub fn relevance_score_at(&self, now: DateTime<Utc>) -> f32

Calculate relevance score at a given timestamp

Use this variant in sort comparators to avoid repeated Utc::now() syscalls.

pub fn relevance_score(&self) -> f32

Calculate relevance score based on recency and importance
