### Custom CSS classes for code blocks
```rust
#![feature(custom_code_classes_in_docs)]
/// ```custom,{class=language-c}
/// int main(void) { return 0; }
/// ```
pub struct Bar;
```
The text `int main(void) { return 0; }` is rendered without highlighting in a code block
with the class `language-c`. This can be used to highlight other languages through JavaScript
libraries for example.
Without the `custom` attribute, it would be generated as a Rust code example with an additional
`language-C` CSS class. Therefore, if you specifically don't want it to be a Rust code example,
don't forget to add the `custom` attribute.
To be noted that you can replace `class=` with `.` to achieve the same result:
```rust
#![feature(custom_code_classes_in_docs)]
/// ```custom,{.language-c}
/// int main(void) { return 0; }
/// ```
pub struct Bar;
```
To be noted, `rust` and `.rust`/`class=rust` have different effects: `rust` indicates that this is
a Rust code block whereas the two others add a "rust" CSS class on the code block.
You can also use double quotes:
```rust
#![feature(custom_code_classes_in_docs)]
/// ```"not rust" {."hello everyone"}
/// int main(void) { return 0; }
/// ```
pub struct Bar;
```
