Trait Preprocessor 

pub trait Preprocessor {
    // Required methods
    fn name(&self) -> &str;
    fn run(&self, ctx: &PreprocessorContext, book: Book) -> Result<Book>;

    // Provided method
    fn supports_renderer(&self, _renderer: &str) -> Result<bool> { ... }
}

An operation which is run immediately after loading a book into memory and before it gets rendered.

Types that implement the Preprocessor trait can be used with MDBook::with_preprocessor to programmatically add preprocessors.

Required Methods

fn name(&self) -> &str

Get the Preprocessor’s name.

fn run(&self, ctx: &PreprocessorContext, book: Book) -> Result<Book>

Run this Preprocessor, allowing it to update the book before it is given to a renderer.

Provided Methods

fn supports_renderer(&self, _renderer: &str) -> Result<bool>

A hint to MDBook whether this preprocessor is compatible with a particular renderer.

By default, always returns true.
