Struct Reading 

pub struct Reading {
    pub domain: String,
    pub label: String,
    pub value: f64,
    pub unit: &'static str,
}

One named scalar from one domain at one instant.

Deliberately flat and owned: it crosses a layer boundary, gets written to a CSV column and a chart legend, and neither of those wants a borrow into a running simulation.

Fields

domain: String

Which domain it came from. Filled in by the domain, because only it knows its own name.

label: String

What it is — "mean", "peak", "reserve", a node’s name.

value: f64

The value, in SI, with one exception this workspace has already made everywhere else: temperatures are celsius, because that is the unit a column of them is read in.

unit: &'static str

The unit, for a header row or an axis. &'static str because a unit is a compile-time fact about the quantity, not data — unlike a domain’s name, which comes from a file.

Implementations

impl Reading

pub fn new( domain: impl Into<String>, label: impl Into<String>, value: f64, unit: &'static str, ) -> Reading

A reading, named.

Trait Implementations

fn clone(&self) -> Reading

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Reading

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

Formats the value using the given formatter.

impl PartialEq for Reading

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

Equality operator ==.
