1//! `MarkdownSource` implementation for `oxios_markdown::KnowledgeBase`.
2//!
3//! Required because of Rust's orphan rule: both the trait
4//! (`MarkdownSource`, defined in `oxios_memory`) and the concrete
5//! type (`KnowledgeBase`, defined in `oxios_markdown`) are foreign.
6//! The wrapper provides a local home for the impl.
7
8/// Thin newtype wrapper around `KnowledgeBase`.
9///
10/// Pass to `AutoMemoryBridge::with_knowledge_base()`:
11/// ```ignore
12/// bridge.with_knowledge_base(Arc::new(MarkdownKnowledgeBase(kb)))
13/// ```
