Struct PricingTable 

pub struct PricingTable { /* private fields */ }

In-memory pricing table loaded from model_pricing for fast lookups.

Implementations

impl PricingTable

pub fn load(conn: &FrankenConnection) -> Result<Self>

Load all pricing entries from the database.

pub fn franken_load(conn: &FrankenConnection) -> Result<Self>

Load all pricing entries from a frankensqlite connection.

pub fn lookup( &self, model_name: &str, message_day_id: i64, ) -> Option<&PricingEntry>

Look up the best pricing entry for a given model name and date.

Selection rules:

1. Pattern must match model_name (SQL LIKE semantics).
2. effective_day_id must be <= message_day_id.
3. Among matches, prefer the most recent effective_date.
4. Tie-break by pattern specificity (longest pattern wins).

pub fn compute_cost( &self, model_name: Option<&str>, message_day_id: i64, input_tokens: Option<i64>, output_tokens: Option<i64>, cache_read_tokens: Option<i64>, cache_creation_tokens: Option<i64>, ) -> Option<f64>

Compute estimated cost in USD for a set of token counts.

Returns None if no pricing entry matches or if no token counts are available.

pub fn is_empty(&self) -> bool

Whether the pricing table has any entries.
