Struct Pricing 

pub struct Pricing { /* private fields */ }

Every model’s pricing, keyed by model id.

Loaded rather than compiled in — see the module documentation.

Implementations

impl Pricing

pub fn new() -> Self

An empty catalogue.

pub fn from_json(json: &str) -> Result<Self, PricingError>

Read a catalogue from JSON.

Errors

PricingError::Malformed if the document is not a map of model id to cost model.

pub fn to_json(&self) -> Result<String, PricingError>

Render the catalogue back to JSON.

Errors

PricingError::Malformed if the catalogue cannot be encoded.

pub fn with(self, model: impl Into<String>, cost: CostModel) -> Self

Add or replace one model’s pricing.

pub fn get(&self, model: &str) -> Option<&CostModel>

What a model charges, if the catalogue knows it.

pub fn models(&self) -> impl Iterator<Item = (&str, &CostModel)>

Every model priced, in id order.

pub fn len(&self) -> usize

How many models are priced.

pub fn is_empty(&self) -> bool

Whether nothing is priced.

pub fn stale(&self, horizon: AsOf) -> Vec<&str>

The models whose figures predate horizon, in id order.
