DocumentContentHandlers

Struct DocumentContentHandlers

pub struct DocumentContentHandlers<'h, H: HandlerTypes = LocalHandlerTypes> {
    pub doctype: Option<H::DoctypeHandler<'h>>,
    pub comments: Option<H::CommentHandler<'h>>,
    pub text: Option<H::TextHandler<'h>>,
    pub end: Option<H::EndHandler<'h>>,
}

Expand description

Specifies document-level content handlers.

Some content can’t be captured by CSS selectors as it lays outside of content of any of the HTML elements. Document-level handlers allow capture such a content:

<!doctype html>
<!--
    I can't be captured with a selector, but I can be
    captured with a document-level comment handler
-->
<html>
<!-- I can be captured with a selector -->
</html>

Fields§

§doctype: Option<H::DoctypeHandler<'h>>

Doctype handler. See doctype! and HandlerTypes::DoctypeHandler.

§comments: Option<H::CommentHandler<'h>>

Comment handler. See doc_comments! and HandlerTypes::CommentHandler.

§text: Option<H::TextHandler<'h>>

Text handler that receives fragments of text nodes. See TextChunk, doc_text!, and HandlerTypes::TextHandler.

§end: Option<H::EndHandler<'h>>

End handler. See HandlerTypes::EndHandler.

Implementations§

impl<'h, H: HandlerTypes> DocumentContentHandlers<'h, H>

pub fn doctype(self, handler: impl IntoHandler<H::DoctypeHandler<'h>>) -> Self

Sets a handler for the document type declaration.

pub fn comments(self, handler: impl IntoHandler<H::CommentHandler<'h>>) -> Self

Sets a handler for all HTML comments present in the input HTML markup.

pub fn text(self, handler: impl IntoHandler<H::TextHandler<'h>>) -> Self

Sets a handler for all text chunks present in the input HTML markup.

pub fn end(self, handler: impl IntoHandler<H::EndHandler<'h>>) -> Self

Sets a handler for the document end, which is called after the last chunk is processed.
