LinkExtractor

nexo_core::link_understanding

Struct LinkExtractor 

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

In-memory cache + HTTP client. Held by the runtime as Arc<LinkExtractor> and shared across sessions; the extractor owns its rate limiter so concurrent turns don’t stampede.

Implementations§

Source§

impl LinkExtractor

Source

pub fn new(cfg: &LinkUnderstandingConfig) -> Self

Source

pub fn cache_capacity(&self) -> usize

Capacity of the in-memory cache (for tests / diagnostics).

Source

pub async fn fetch( &self, url: &str, cfg: &LinkUnderstandingConfig, ) -> Option<LinkSummary>

Fetch + extract, honouring the cache. Returns None on any error — the caller (llm_behavior) drops the URL from the rendered block silently.
