Struct PatternDecoherence 

pub struct PatternDecoherence {
    pub id: u64,
    pub t1: Duration,

    pub created_at: Instant,
    pub last_retrieved: Instant,

}

Per-pattern decoherence state

Fields

id: u64

Pattern id

t1: Duration

T1 relaxation time (energy/existence decay)

t2: Duration

T2 dephasing time (detail/coherence decay)

created_at: Instant

Initial creation time

last_retrieved: Instant

Last retrieval time (refreshes coherence)

phi: f64

Φ value at creation — high Φ → longer coherence

retrieval_count: u32

Retrieval count (higher count → refreshed T1)

Implementations

impl PatternDecoherence

pub fn new(id: u64, phi: f64) -> Self

pub fn refresh(&mut self)

Refresh coherence on retrieval (use-dependent plasticity analog)

pub fn coherence_amplitude(&self) -> f64

Current T2 coherence amplitude (1.0 = fully coherent, 0.0 = decoherent)

pub fn existence_probability(&self) -> f64

Current T1 existence probability (1.0 = exists, 0.0 = relaxed/forgotten)

pub fn decoherence_score(&self) -> f64

Combined decoherence score for eviction decisions. Low score → candidate for eviction.

pub fn should_evict(&self, threshold: f64) -> bool

Should this pattern be evicted?

Trait Implementations

impl Clone for PatternDecoherence

fn clone(&self) -> PatternDecoherence

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PatternDecoherence

fn fmt(&self, f: &mut Formatter<'_>) -> Result
