Struct StreamTelemetry 

pub struct StreamTelemetry {
    pub matches: u32,
    pub home_wins: u32,
    pub draws: u32,
    pub away_wins: u32,
    pub goals: u32,
    pub shots: u32,
    pub shots_on_target: u32,
    pub goals_by_kind: BTreeMap<ShotKind, u32>,
    pub goals_by_source: BTreeMap<ShotSource, u32>,
    pub home_events: u32,
    pub away_events: u32,
    pub by_formation: BTreeMap<u8, FormationStats>,
}

Accumulates match aggregates directly from MatchOutcome traces — everything SeasonTelemetry can’t see because the fold discards the stream. Mirrors the notebook’s report() fields.

Fields

matches: u32

home_wins: u32

draws: u32

away_wins: u32

goals: u32

shots: u32

shots_on_target: u32

goals_by_kind: BTreeMap<ShotKind, u32>

goals_by_source: BTreeMap<ShotSource, u32>

Goals keyed by arrival route (MATCH_MODEL.md §5) — what makes the wide-origin-goal-share target (cross + cutback, §8) computable, distinct from goals_by_kind’s coarser Finish/Header/LongShot split.

home_events: u32

A crude possession proxy: total stream events attributed to each side (more events ⇒ more time on the ball / advancing it).

away_events: u32

by_formation: BTreeMap<u8, FormationStats>

Keyed by Lineup::formation index into FORMATIONS.

Implementations

impl StreamTelemetry

pub fn record( &mut self, outcome: &MatchOutcome, home_formation: u8, away_formation: u8, )

Fold one match’s trace in. home_formation/away_formation are the Lineup::formation index each side fielded, for the per-formation breakdown (MATCH_MODEL.md §10 item 1’s diagnostic).

pub fn goals_per_match(&self) -> f64

pub fn shots_per_match(&self) -> f64

pub fn home_win_rate(&self) -> f64

pub fn draw_rate(&self) -> f64

pub fn away_win_rate(&self) -> f64

pub fn shot_on_target_rate(&self) -> f64

pub fn conversion_rate(&self) -> f64

pub fn headed_goal_share(&self) -> f64

Share of goals scored via ShotKind::Header — the headed-goal-share calibration target (MATCH_MODEL.md §8).

pub fn wide_origin_goal_share(&self) -> f64

Share of goals arriving via ShotSource::Cross or Cutback — the wide-origin-goal-share calibration target (MATCH_MODEL.md §8: “cross + cutback”), 25-35%.

pub fn home_possession_share(&self) -> f64

Home share of the possession-proxy event count.

Trait Implementations

impl Clone for StreamTelemetry

fn clone(&self) -> StreamTelemetry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamTelemetry

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

Formats the value using the given formatter.

impl Default for StreamTelemetry

fn default() -> StreamTelemetry

Returns the “default value” for a type.
