Struct PartialUsage 

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

Partial usage data from a failed agent invocation.

When an agent step fails (e.g. structured output extraction), the CLI may still report cost, duration, and token counts. This struct carries those values so callers can persist them even on error paths.

Fields

cost_usd: Option<f64>

Total cost in USD reported by the CLI.

duration_ms: Option<u64>

Wall-clock duration reported by the CLI, in milliseconds.

input_tokens: Option<u64>

Input tokens consumed before the failure.

output_tokens: Option<u64>

Output tokens generated before the failure.

Trait Implementations

impl Debug for PartialUsage

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

Formats the value using the given formatter.

impl Default for PartialUsage

fn default() -> PartialUsage

Returns the “default value” for a type.
