Struct genpdf::SimplePageDecorator

pub struct SimplePageDecorator { /* fields omitted */ }

Prepares a page of a document with margins and a header.

Per default, this decorator does not modify the page. If margins have been set with the set_margins method, they are applied to every page. If a header callback is configured with the set_header method, it will be called for every page and its return value will be rendered at the beginning of the page (after the margins have been applied).

Implementations

impl SimplePageDecorator

pub fn new() -> SimplePageDecorator

Creates a new page decorator that does not modify the page.

pub fn set_margins(&mut self, margins: impl Into<Margins>)

Sets the margins for all pages of this document.

If this method is not called, the full page is used.

pub fn set_header<F, E>(&mut self, cb: F) where
    F: Fn(usize) -> E + 'static,
    E: Element + 'static, 

Sets the header generator for this document.

The given closure will be called once per page. Its argument is the page number (starting with 1), and its return value will be rendered at the top of the page. The document content will start directly after the element.
