Struct Episode 

pub struct Episode {
    pub start_ts: u64,
    pub end_ts: Option<u64>,
    pub grammar_state: GrammarState,
    pub reason_code: ReasonCode,
    pub primary_source: ResidualSource,
    pub max_drift: f64,
    pub max_slew: f64,
    pub max_residual: f64,
    pub sample_count: u32,
}

A structural episode: a contiguous period of a specific grammar state.

This is the operator-facing output of the DSFB engine. Each episode carries the full audit context needed to understand why the classification was made and what structural pattern was detected.

Fields

start_ts: u64

Monotonic timestamp when this episode began (nanoseconds).

end_ts: Option<u64>

Monotonic timestamp when this episode ended (nanoseconds). None if the episode is still open.

grammar_state: GrammarState

Grammar state during this episode.

reason_code: ReasonCode

Reason code from the heuristics bank match.

primary_source: ResidualSource

Which residual source(s) contributed to this classification.

max_drift: f64

Maximum absolute drift observed during this episode.

max_slew: f64

Maximum absolute slew observed during this episode.

max_residual: f64

Maximum absolute residual observed during this episode.

sample_count: u32

Number of observation samples in this episode.

Implementations

impl Episode

pub fn duration_ns(&self) -> Option<u64>

Duration of this episode in nanoseconds, or None if still open.

pub fn is_open(&self) -> bool

Whether this episode is still open (no end timestamp).

pub fn is_anomalous(&self) -> bool

Whether this episode represents a structural anomaly (Boundary or Violation).

Trait Implementations

impl Clone for Episode

fn clone(&self) -> Episode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Episode

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

Formats the value using the given formatter.
