Function: withModelSource()

function withModelSource<T>(
  env: TransformersEnvLike,
  hook: TransformersJsModelSource,
  load: () => Promise<T>,
): Promise<T>;

Defined in: src/batteries/llm/transformers_js/model_source.ts:158

Run load() with hook installed on env, then restore — serialized against every other withModelSource call so concurrent adapter loads never clobber the global env. The hook is only active for the duration of load(); after it resolves (or rejects) the prior env cache config is restored even on error.
