HeadParser

browser_cat::html

Struct HeadParser 

Source 
pub struct HeadParser { /* private fields */ }
Expand description

Incrementally parses an HTML stream, separating the <head> from the <body>. Feed chunks via HeadParser::feed until HeadParser::complete returns true, then call HeadParser::head and HeadParser::take_body.

Also detects whether the input is HTML at all: if the first non-whitespace character is not < the document is treated as plain text.

Implementations§

Source§

impl HeadParser

Source

pub fn new() -> Self

Source

pub fn feed(&mut self, data: &str) -> bool

Feed the next chunk of input. Returns true once the body has started (i.e. HeadParser::complete would return true).

Source

pub fn complete(&self) -> bool

True once the first body character has been seen.

Source

pub fn is_html(&self) -> bool

True if the input looks like HTML (first non-whitespace char is <).

Source

pub fn head(&self) -> String

Inner content of <head> (stripped of structural tags like DOCTYPE, <html>, <head>).

Source

pub fn take_body(&mut self) -> String

Take and return all body content seen so far, leaving the parser empty. The caller is responsible for injecting a <body> wrapper if needed.
