Struct CostEstimate 

pub struct CostEstimate {
    pub input_cost: f64,
    pub output_cost: f64,
    pub total_cost: f64,
    pub currency: String,
}

Estimated request cost, split into input/output components.

Prices are in USD per million tokens — the standard unit advertised by Anthropic, OpenAI, and Bedrock.

Examples

use codetether_agent::telemetry::{CostEstimate, TokenCounts};

let cost = CostEstimate::from_tokens(
    &TokenCounts::new(2_000_000, 1_000_000),
    3.00,
    15.00,
);
assert!((cost.total_cost - 21.0).abs() < 1e-6);
assert_eq!(cost.format_smart(), "$21.00");

Fields

input_cost: f64

Cost attributable to input tokens.

output_cost: f64

Cost attributable to output tokens.

total_cost: f64

input_cost + output_cost.

currency: String

ISO-4217 currency code (always "USD" today).

Implementations

impl CostEstimate

pub fn from_tokens( tokens: &TokenCounts, input_price: f64, output_price: f64, ) -> Self

Compute a cost estimate from token counts and per-million prices.

pub fn format_currency(&self) -> String

Always 4 decimal places: "$0.0042".

pub fn format_smart(&self) -> String

Sub-cent amounts use 4 decimals; >= $0.01 uses 2.
