Struct PricingTable 

pub struct PricingTable { /* private fields */ }

Provider/model pricing table.

Lookup keys on (provider, model); entries whose provider is None act as model-only fallbacks (matched when no provider-qualified entry exists).

Implementations

impl PricingTable

pub fn new() -> Self

Empty table (every call prices at zero).

pub fn builtin() -> Self

Built-in snapshot of common models (USD/1K, as of 2026-09).

This is a convenience seed, not a maintained source of truth: provider prices change frequently. Fetch a current crate::model_registry::ModelRegistry remotely and convert it with PricingTable::from_registry for production accounting.

pub fn with( self, provider: impl Into<String>, model: impl Into<String>, price: ModelPrice, ) -> Self

Adds/replaces a qualified entry; returns the table for chaining.

pub fn with_model_only( self, model: impl Into<String>, price: ModelPrice, ) -> Self

Adds/replaces a model-only fallback entry.

pub fn insert( &mut self, provider: Option<impl Into<String>>, model: impl Into<String>, price: ModelPrice, )

Inserts an entry. provider = None registers a model-only fallback.

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

Lookup: provider-qualified first, then the model-only fallback.

pub fn len(&self) -> usize

Number of registered entries.

pub fn is_empty(&self) -> bool

Whether no entry is registered.

pub fn from_registry(registry: &ModelRegistry) -> Self

Builds a table from a model registry (qualified entries only).
