pub fn run_profile_backtest(
    corpus: &[BacktestCase],
    profiles: &[AnalyzerProfile],
) -> Result<BacktestReport, BacktestError>

Replay historical HAR cases against existing analyzer profiles.

Errors

Returns BacktestError::EmptyCorpus when no cases are supplied, BacktestError::EmptyProfiles when no profiles are supplied, and BacktestError::Har when any HAR payload cannot be parsed.

Example

use stygian_charon::AnalyzerProfile;
use stygian_charon::AnalyzerVersion;
