LOCOMO — estimates cost/time to regenerate code with an LLM.

Per scc’s LOCOMO model: density = complexity / code_lines cFactor = 1 + √density × complexity_weight iFactor = base_iterations + √density × iteration_weight outputTokens = code × tokens_per_line × iFactor inputTokens = code × input_per_line × cFactor × iFactor cost = input_tokens/1M × input_price + output_tokens/1M × output_price generation_seconds = output_tokens / tokens_per_second review_hours = code × minutes_per_line / 60

Trait Implementations

impl Default for LocomoModel

fn default() -> Self

Returns the “default value” for a type.

impl EstimationModel for LocomoModel

fn estimate_effort(&self, metrics: &CodeMetrics) -> f64

Effort = human review hours as person-months (160 hrs/month).

fn estimate_schedule(&self, _effort_months: f64, metrics: &CodeMetrics) -> f64

Schedule = LLM generation time in months.

fn estimate_cost( &self, _effort_months: f64, metrics: &CodeMetrics, _cost_config: &CostConfig, ) -> f64

Cost = LLM API cost (overrides salary-based default).

fn name(&self) -> &str

Model display name.

fn display_params(&self) -> Vec<(String, String)>

Key parameters for display in report footer.

fn estimate_people(&self, effort_months: f64, schedule_months: f64) -> f64

Estimate people required. Default: effort / schedule.
