Struct Models 

pub struct Models { /* private fields */ }

Thread-safe model registry used by the engine.

It maintains two layers:

• model: the primary default model for general requests
• models: a label-based map for selecting specific models

The dedicated primary slot can be set explicitly via Models::set_model or derived from the special label primary in the label map. This keeps direct lookup (get) separate from default-routing (get_model).

Implementations

impl Models

pub fn from_clone(other: &Models) -> Self

Creates a new Models instance by cloning the internal state of another Models instance.

pub fn replace(&self, other: &Models)

Replaces this registry with a clone of another Models instance.

pub fn from_configs(configs: &[ModelConfig], http_client: Client) -> Self

Builds a registry from model configs by registering every resolved label.

pub fn contains(&self, label: &str) -> bool

Returns whether a label exists in the direct lookup table.

pub fn model_names(&self) -> BTreeSet<String>

Returns the set of all registered model names across all labels.

pub fn set_model(&self, model: Model)

Sets the primary default model without mutating the label map.

pub fn set(&self, label: String, model: Model)

Inserts or updates a single labeled model.

The special label primary also updates the dedicated routing slot. If no primary exists yet, any inserted model is promoted to become the primary default.

pub fn get(&self, label: &str) -> Option<Model>

Returns a model by lowercase label if it exists.

This is a direct lookup only and never falls back to default routing.

pub fn get_model(&self) -> Option<Model>

Returns the primary model if available; otherwise returns any remaining labeled model.

pub fn resolve(&self, label: &str) -> Option<Model>

Resolves a model for lowercase-label-aware routing.

Resolution order is:

• the exact label match when label is non-empty
• the default routing result from Models::get_model

Trait Implementations

impl Default for Models

fn default() -> Self

Returns the “default value” for a type.
