Struct RecentObservation 

pub struct RecentObservation {
    pub hydro_id: EntityId,
    pub start_date: NaiveDate,
    pub end_date: NaiveDate,
    pub value_m3s: f64,
}

Observed inflow for a single hydro plant over a specific date range.

Used to seed the lag accumulator when a study begins mid-season. Each entry represents the average inflow (in m³/s) observed between start_date (inclusive) and end_date (exclusive) for one hydro. Multiple entries per hydro are allowed for rolling revisions with several observed weeks.

Date ranges for the same hydro must not overlap; adjacent ranges (start_date == previous end_date) are accepted.

Fields

hydro_id: EntityId

Hydro plant identifier. Must reference a hydro entity in the system.

start_date: NaiveDate

Start of the observation period (inclusive).

end_date: NaiveDate

End of the observation period (exclusive). Must be after start_date.

value_m3s: f64

Average inflow observed during the period, in m³/s. Must be finite and non-negative.

Trait Implementations

impl Clone for RecentObservation

fn clone(&self) -> RecentObservation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecentObservation

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

Formats the value using the given formatter.

impl PartialEq for RecentObservation

fn eq(&self, other: &RecentObservation) -> 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.
