Implementations

impl CostTable

pub fn load() -> Result<Self>

Load from bundled assets/cost.toml.

pub fn estimate( &self, model: Option<&str>, tokens_in: u32, tokens_out: u32, ) -> i64

Estimate cost in cost_usd_e6 units. If model is None or not found, falls back to “cursor” heuristic entry. If tokens_in == 0 and tokens_out == 0 (Cursor: no native tokens), uses avg_tokens_per_turn from the matched entry.

pub fn find(&self, model: &str) -> Option<&ModelPrice>

pub fn estimate_tail_event_cost_usd_e6( &self, model: Option<&str>, tokens_in: Option<u32>, tokens_out: Option<u32>, reasoning_tokens: Option<u32>, ) -> Option<i64>

Transcript tail rows: charge only when at least one usage field is set and prompt + output (including reasoning) are not all zero. Omits proxy-style avg_tokens_per_turn fallback so thousands of tool lines do not each get a heuristic charge.
