Struct StreamingHtmlParser

Source

pub struct StreamingHtmlParser { /* private fields */ }

Expand description

Streaming HTML parser that processes content incrementally.

Buffers HTML chunks as they arrive and parses when a complete document is detected. This is useful for processing HTML from streaming sources like HTTP responses.

§Examples

use crawlkit_engine::parser::StreamingHtmlParser;

let mut parser = StreamingHtmlParser::new();
parser.feed("<!DOCTYPE html><html><head><title>Test</title></head>");
parser.feed("<body><h1>Hello</h1></body></html>");

assert!(parser.has_complete_document());
let page = parser.parse().unwrap();
assert_eq!(page.meta.title.as_deref(), Some("Test"));

Implementations§

Source §

impl StreamingHtmlParser

Source

pub fn new() -> Self

Create a new streaming parser.

Source

pub fn feed(&mut self, chunk: &str)

Feed a chunk of HTML content into the parser.

The chunk is appended to the internal buffer for later parsing.

Source

pub fn has_complete_document(&self) -> bool

Check if the accumulated content contains a complete HTML document.

Returns true if the buffer contains </html> or </body> tags, indicating the document is likely complete.

Source

pub fn parse(&mut self) -> Result<ParsedPage, ParseError>

Parse the accumulated HTML content.

Delegates to HtmlParser::parse with a blank URL. Returns a ParsedPage containing all extracted SEO data.

§Errors

Returns ParseError if parsing fails (currently never happens).

Source

pub fn buffer_size(&self) -> usize

Get the current buffer size in bytes.

Source

pub fn clear(&mut self)

Clear the internal buffer.

Source

pub fn buffer(&self) -> &str

Get a reference to the buffered content.

Source

pub fn into_inner(self) -> String

Consume the parser and return the buffered content.
