Struct ModelRegistry 

pub struct ModelRegistry { /* private fields */ }

Provider/model catalog. Cheap to clone (entries shared via Arc).

Implementations

impl ModelRegistry

pub fn new() -> Self

Empty registry.

pub fn register(&mut self, info: ModelInfo)

Adds/overwrites one entry.

pub fn with(self, info: ModelInfo) -> Self

Builder-style entry registration.

pub fn merge(&mut self, other: ModelRegistry)

Merges every entry of other into this registry (other wins on key collision — a remote catalog can therefore override built-in prices).

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

Lookup by provider + model id.

pub fn get_by_key(&self, key: &str) -> Option<&Arc<ModelInfo>>

Lookup by canonical "<provider>/<id>" key.

pub fn models(&self) -> impl Iterator<Item = &Arc<ModelInfo>>

All registered entries (arbitrary order).

pub fn models_of<'a>( &'a self, provider: &'a str, ) -> impl Iterator<Item = &'a Arc<ModelInfo>> + 'a

Entries of one provider.

pub fn len(&self) -> usize

Number of entries.

pub fn is_empty(&self) -> bool

Whether the registry is empty.

pub fn from_json(json: &str) -> Result<Self, CostError>

Parses a remote/JSON catalog ({"version":..,"models":[...]} or a bare [ModelInfo] array).

pub fn to_json(&self) -> Result<String, CostError>

Serializes the registry to the enveloped catalog JSON.

pub async fn fetch(url: &str) -> Result<Self, CostError>

Downloads and parses a remote catalog with a fresh blocking-capable reqwest client.

pub async fn fetch_with_client( client: &Client, url: &str, ) -> Result<Self, CostError>

Downloads and parses a remote catalog with a caller-provided client (shared connection pool, custom timeouts/proxies/auth headers).
