Enum FilterTerm 

pub enum FilterTerm {
    Exists(String),
    Eq(String, Value),
    In(String, Vec<Value>),
    Range {
        key: String,
        min: Option<f64>,
        max: Option<f64>,
    },
}

One AND-ed condition applied to a candidate memory’s metadata during filtered recall (Phase 12.6). Terms are combined conjunctively — a memory passes the filter only if every term evaluates true against its metadata map. See Filter for the surface API.

Values use serde_json::Value so the same term shape serializes cleanly through the MCP / Python / CLI bridges without a parallel enum per surface.

Variants

Exists(String)

The memory’s metadata[key] must be set to any value.

Eq(String, Value)

metadata[key] must equal this JSON value (strict JSON equality: strings compare case-sensitively, numbers compare as f64).

In(String, Vec<Value>)

metadata[key] must equal one of these JSON values.

Range

metadata[key] must be a number in [min, max] (inclusive on both ends; None on either bound means “no bound on that side”). A non-numeric metadata value fails the term.

Fields

key: String

Metadata key.

min: Option<f64>

Lower bound (inclusive) — None means unbounded below.

max: Option<f64>

Upper bound (inclusive) — None means unbounded above.
