Struct GraphDecay 

Source 
pub struct GraphDecay { /* private fields */ }
Expand description

Recency-decay parameters for graph traversal (ADD task graph-decay-recency, contract v1). Maps to Moon’s GRAPH.QUERY ... --decay <λ> [--time-weight <w>] read-path clause: effective edge cost = |weight| + λ·w·age_seconds.

Fields are PRIVATE — validity by construction. new rejects non-finite or negative λ; with_time_weight rejects non-finite or non-positive w, so a time weight without a decay rate is unrepresentable.

Implementations§

Source§

impl GraphDecay

Source

pub fn new(lambda: f64) -> Result<GraphDecay, StorageError>

Construct with a decay rate λ. Accepts finite λ ≥ 0 only (λ = 0 is valid and decay-neutral, matching Moon’s server-side validation).

Source

pub fn with_time_weight(self, w: f64) -> Result<GraphDecay, StorageError>

Set the time-weight multiplier w. Accepts finite w > 0 only.

Source

pub fn lambda(&self) -> f64

The decay rate λ (finite, ≥ 0).

Source

pub fn time_weight(&self) -> Option<f64>

The time-weight multiplier, if set (finite, > 0).
