Code blocks and includes
Markdown fenced code blocks (we will call them code examples as well) are inserted between two code fences (e.g. sets of triple backticks), with an optional info string (a.k.a. attributes ) after the first backtick group:
```rust
fn main() {}
```
mdbook allows including files into your book via include statements. mdbook interprets included files as Markdown. Since the include syntax is usually used for inserting code snippets and examples, it is often wrapped between two sets of backticks.
```rust
{{# include file.rs}}
```
