Struct ModelRegistry 

pub struct ModelRegistry { /* private fields */ }

A searchable collection of model entries.

Implementations

impl ModelRegistry

pub fn bundled() -> &'static Self

Returns the compile-time bundled registry.

pub fn from_litellm_json(json: &[u8]) -> Self

Build a registry from parsed LiteLLM JSON bytes.

pub fn tier(&self, model_id: &str) -> ModelTier

Capability/cost tier of a model, classified against this registry’s chat-model price distribution. Unknown models classify as ModelTier::Balanced.

pub fn tier_of(&self, entry: &ModelEntry) -> ModelTier

Capability/cost tier of a specific registry entry.

pub fn lookup(&self, model_id: &str) -> Option<&ModelEntry>

Exact match on the LiteLLM key, then version-suffix normalization.

Normalization strips trailing -vN[:M], -YYYYMMDD, -YYYY-MM-DD, @YYYYMMDD, and compact -MMDD checkpoint dates, rewrites a vMAJOR-MINOR token to vMAJOR.MINOR, and collapses vMAJOR.MINOR to vMAJOR when the dotted form is also a miss, so dated or versioned aliases resolve to the base model’s record. It never binds a bare query to a provider-scoped key (github_copilot/claude-sonnet-4 only answers github_copilot/ lookups) and never changes the model family: an unknown or retired ID returns None.

pub fn models_for_provider( &self, provider: &Provider, ) -> impl Iterator<Item = &ModelEntry>

All models from a given provider.

pub fn models_by_mode( &self, mode: ModelMode, ) -> impl Iterator<Item = &ModelEntry>

All models matching a given mode.

pub fn models_with_ability( &self, ability: Ability, ) -> impl Iterator<Item = &ModelEntry>

All models with a specific ability.

pub fn all(&self) -> impl Iterator<Item = &ModelEntry>

Iterate over all entries.

pub const fn len(&self) -> usize

Total number of entries.

pub const fn is_empty(&self) -> bool

Whether the registry is empty.
