Struct TrendResult 

pub struct TrendResult {
    pub snapshot_count: usize,
    pub pattern_entropy_slope: Option<f64>,
    pub convention_drift_slope: Option<f64>,
    pub coupling_slope: Option<f64>,
    pub community_count_slope: Option<f64>,
}

Per-dimension trend data over a window of consecutive snapshots.

All delta fields are the slope (change per snapshot interval) of a linear regression over the window, or None when there are fewer than two snapshots to compare.

Examples

use sdivi_snapshot::trend::compute_trend;

let result = compute_trend(&[], None);
assert_eq!(result.snapshot_count, 0);
assert!(result.pattern_entropy_slope.is_none());

Fields

snapshot_count: usize

Number of snapshots in the analysis window.

pattern_entropy_slope: Option<f64>

Slope of pattern_entropy_delta across the window (nats / snapshot).

convention_drift_slope: Option<f64>

Slope of convention_drift_delta across the window.

coupling_slope: Option<f64>

Slope of coupling_delta across the window.

community_count_slope: Option<f64>

Slope of community_count_delta across the window.

Trait Implementations

impl Clone for TrendResult

fn clone(&self) -> TrendResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TrendResult

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TrendResult

fn deserialize<__D>( __deserializer: __D, ) -> Result<TrendResult, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TrendResult

fn eq(&self, other: &TrendResult) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TrendResult

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
