Struct Pricing 

pub struct Pricing {
    pub input: f64,
    pub output: f64,
    pub cache_read: f64,
    pub cache_write: f64,
}

USD per million tokens. Prices change often, so Cairn never hardcodes them; set them from your provider’s current price sheet. A model that is genuinely free should say so explicitly with Pricing::new(0.0, 0.0).

Fields

input: f64

output: f64

cache_read: f64

cache_write: f64

Implementations

pub fn new(input: f64, output: f64) -> Self

pub fn cost(&self, u: &Usage) -> f64

pub fn max(self, other: Pricing) -> Pricing

Field-wise maximum: a conservative price when the serving model of several is not known.
