Implementations

impl FallbackRenderer

pub fn new( config: &RendererConfig, user_agent: &str, proxy: Option<&str>, stealth: &StealthConfig, ) -> Self

pub async fn fetch( &self, url: &str, headers: &HashMap<String, String>, render_js: Option<bool>, wait_for_ms: Option<u64>, ) -> CrwResult<FetchResult>

Fetch a URL with smart mode: HTTP first, then JS if needed.

When render_js is None (auto-detect), the renderer also escalates to JS rendering if the HTTP response looks like an anti-bot challenge page (Cloudflare “Just a moment…”, etc.). The CDP renderer has built-in challenge retry logic that waits for non-interactive JS challenges to auto-resolve.

pub async fn check_health(&self) -> HashMap<String, bool>

Check availability of all renderers.
