Struct EvaluationMetrics 

pub struct EvaluationMetrics {
    pub duration_ms: f64,
    pub input_tokens: Option<u64>,
    pub output_tokens: Option<u64>,
    pub cost_usd: Option<f64>,
}

Non-sensitive resource evidence for one successful target execution.

Fields

duration_ms: f64

Host-observed target duration in milliseconds.

input_tokens: Option<u64>

Provider-reported input tokens when available.

output_tokens: Option<u64>

Provider-reported output tokens when available.

cost_usd: Option<f64>

Provider- or application-reported cost in US dollars.

Implementations

impl EvaluationMetrics

pub fn new(duration_ms: f64) -> Result<Self, EvaluationError>

Creates metrics with host-observed duration and no Provider usage.

Errors

Returns an error when duration is negative or non-finite.

pub const fn with_tokens(self, input_tokens: u64, output_tokens: u64) -> Self

Adds Provider token usage.

pub fn with_cost_usd(self, cost_usd: f64) -> Result<Self, EvaluationError>

Adds monetary cost.

Errors

Returns an error when cost is negative or non-finite.
