Traits

CompletionProvider

Tool declarations are the one and only view providers have into the user’s tool collections. The trait intentionally exposes nothing about execution, metadata, or strategy — providers translate declarations to their wire format and nothing else. For the builder-side collection API, see crate::types::tools.

EmbeddingsProvider

TypedCollection

Type-erased view of a tool collection used by the chat loop.
