Struct DecayPolicy 

pub struct DecayPolicy { /* private fields */ }

Governs how memory importance decays over time.

Implementations

impl DecayPolicy

pub fn exponential(half_life_hours: f64) -> Result<Self, AgentRuntimeError>

Create an exponential decay policy with the given half-life in hours.

Arguments

• half_life_hours — time after which importance is halved; must be > 0

Returns

• Ok(DecayPolicy) — on success
• Err(AgentRuntimeError::Memory) — if half_life_hours <= 0

pub fn apply(&self, importance: f32, age_hours: f64) -> f32

Apply decay to an importance score based on elapsed time.

Arguments

• importance — original importance in [0.0, 1.0]
• age_hours — how many hours have passed since the memory was recorded

Returns

Decayed importance clamped to [0.0, 1.0].

pub fn half_life_hours(&self) -> f64

Return the configured half-life in hours.

pub fn decay_item(&self, item: &mut MemoryItem)

Apply decay in-place to a mutable MemoryItem.
