Struct MemoryItem 

pub struct MemoryItem {
    pub key: String,
    pub text: String,
    pub importance: f64,
    pub metadata: HashMap<String, String>,
}

A storable unit of knowledge.

importance is clamped into [0, 1] by the stores; key must be stable within a namespace (re-putting the same key updates the entry).

Fields

key: String

Stable identifier within the namespace.

text: String

The memory text, matched by semantic search.

importance: f64

Importance in [0, 1] (higher resists decay and promotes sooner).

metadata: HashMap<String, String>

Arbitrary structured annotations (user id, source turn, …).

Implementations

impl MemoryItem

pub fn new(key: impl Into<String>, text: impl Into<String>) -> Self

Creates a memory with default importance 0.5 and no metadata.

pub fn with_importance(self, importance: f64) -> Self

Sets the importance (clamped to [0, 1] at write time anyway).

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

Adds one metadata annotation.

pub fn with_metadata(self, metadata: HashMap<String, String>) -> Self

Replaces the whole metadata map.
