Struct lol_html::DocumentContentHandlers

pub struct DocumentContentHandlers<'h> {
    pub doctype: Option<DoctypeHandler<'h>>,
    pub comments: Option<CommentHandler<'h>>,
    pub text: Option<TextHandler<'h>>,
    pub end: Option<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<DoctypeHandler<'h>>

Doctype handler. See DoctypeHandler.

§comments: Option<CommentHandler<'h>>

Comment handler. See CommentHandler.

§text: Option<TextHandler<'h>>

Text handler. See TextHandler.

§end: Option<EndHandler<'h>>

End handler. See EndHandler.

Implementations§

impl<'h> DocumentContentHandlers<'h>

pub fn doctype( self, handler: impl FnMut(&mut Doctype<'_>) -> HandlerResult + 'h ) -> Self

Sets a handler for the document type declaration.

pub fn comments( self, handler: impl FnMut(&mut Comment<'_>) -> HandlerResult + 'h ) -> Self

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

pub fn text( self, handler: impl FnMut(&mut TextChunk<'_>) -> HandlerResult + 'h ) -> Self

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

pub fn end( self, handler: impl FnMut(&mut DocumentEnd<'_>) -> HandlerResult + 'h ) -> Self

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