Struct ModelRegistry 

pub struct ModelRegistry { /* private fields */ }

Concurrent registry of ModelMetadata keyed by model ID.

Implementations

impl ModelRegistry

pub fn new() -> Self

Create an empty registry.

pub fn register(&self, model: ModelMetadata)

Register or replace a model’s metadata.

pub fn get(&self, model_id: &str) -> Option<ModelMetadata>

Look up a model by ID.

pub fn all_models(&self) -> Vec<ModelMetadata>

Return all registered models.

pub fn models_with_capability( &self, cap: &ModelCapability, ) -> Vec<ModelMetadata>

Return non-deprecated models that have cap, sorted by cheapest input cost first.

pub fn cheapest_for_capability( &self, cap: &ModelCapability, min_context: usize, ) -> Option<ModelMetadata>

Return the cheapest model that has cap and fits within min_context tokens.

pub fn best_for_capability( &self, cap: &ModelCapability, min_context: usize, ) -> Option<ModelMetadata>

Return the highest-tier model that has cap and fits within min_context tokens.

pub fn suggest_routing( &self, caps: &[ModelCapability], context_size: usize, budget_usd: Option<f64>, ) -> RoutingHint

Suggest a routing strategy given required capabilities, context size, and optional budget.

pub fn built_in_registry() -> Self

Build a registry pre-populated with well-known models.

pub fn rate_limit_check( &self, model_id: &str, requests_last_minute: u32, tokens_last_minute: u32, ) -> bool

Check whether a model is within its rate limits.

Returns true if the model can accept more requests/tokens, false if a limit is exceeded.

pub fn deprecation_warnings(&self) -> Vec<String>

Return deprecation warning strings for all deprecated models.

Trait Implementations

impl Default for ModelRegistry

fn default() -> Self
