1//! Public error type for provider trait contracts.
2//!
3//! [`ProviderError`] is the concrete error returned by every provider trait
4//! that does not have a domain-specific error of its own (LLM and tool
5//! providers carry their own typed errors — see [`crate::llm`] and
6//! [`crate::tool`]).
7//!
8//! Downstream provider crates that implement these traits convert any
9//! third-party error at the boundary with
10//! `.map_err(|e| ProviderError::Internal(e.to_string()))`.
