pub struct ResourceHandler<'r> {
    pub images: HashMap<String, String>,
    // some fields omitted
}

Resource Handler.

Its task is to make sure that some resource (image, link) is available for the book and to list images used in Markdown files so they can be used for the book

Fields

images: HashMap<String, String>

Maps an original (local) file name to a new file name. Allows to

Methods

impl<'r> ResourceHandler<'r>

fn new(logger: &'r Logger) -> ResourceHandler

Creates a new, empty Resource Handler

fn set_images_mapping(&mut self, b: bool)

Turns on mapping for image files

Argument: an offset (should be book.root)

fn set_base64(&mut self, b: bool)

Sets base64 mode for image mapping

If set to true, instead of returning a destination file path, map_image will include the image as base64

fn map_image<'a>(&'a mut self, file: Cow<'a, str>) -> Cow<'a, str>

Add a local image file and get the resulting transformed file name

fn images_mapping(&self) -> &HashMap<String, String>

Returns an iterator the the images files mapping

fn add_link(&mut self, from: String, to: String)

Add a match between an original file and a dest file

fn get_link<'a>(&'a self, from: &'a str) -> &'a str

Get a destination link from an original link

fn is_local(path: &str) -> bool

Tell whether a file name is a local resource or net

fn add_offset(link_offset: &Path, image_offset: &Path, ast: &mut [Token])

Add a path offset to all linked urls and images src

fn get_files(list: Vec<String>, base: &str) -> Result<Vec<String>>

Get the list of all files, walking recursively in directories

Arguments

• list: a list of files
• base: the path where to get them

Returns

A list of files (relative to base), or an error.
