ReadabilityOptions control extraction.

The defaults are conservative. They favor article pages with enough text to be useful and avoid exposing internal scoring knobs unless they affect common integration cases.

#![allow(unused)]
fn main() {
use lectito::ReadabilityOptions;

let options = ReadabilityOptions {
    char_threshold: 800,
    nb_top_candidates: 8,
    content_selector: Some("article".to_string()),
    site_profiles: Vec::new(),
    ..ReadabilityOptions::default()
};
}

Fields:

Field	Default	Meaning
`max_elems_to_parse`	`None`	Reject documents above this element count.
`nb_top_candidates`	`5`	Number of high-scoring candidates to consider.
`char_threshold`	`500`	Minimum extracted text length for an accepted attempt.
`content_selector`	`None`	CSS selector to prefer as the content root.
`site_profiles`	`[]`	TOML site profiles for host-scoped extraction hints.
`mobile_viewport_width`	`Some(480)`	Width used by recovery rules for mobile snapshots.
`classes_to_preserve`	`[]`	Class names kept during cleanup.
`keep_classes`	`false`	Keep all class attributes.
`disable_json_ld`	`false`	Skip JSON-LD metadata extraction.
`link_density_modifier`	`0.0`	Adjust link-density cleanup tolerance.

Prefer content_selector when you already know the page shape. It is clearer than trying to tune scores around a stable document layout.

Use site_profiles when you want the same kind of override to apply by URL host, or when you need removal selectors and metadata hints alongside content roots. Profiles are attempted before generic scoring, but weak profile output falls back to the generic extractor.

Use max_elems_to_parse as a guardrail for untrusted input. It rejects very large documents before extraction work continues.

ReadableOptions controls is_probably_readable.

Lower min_content_length for short posts or documentation pages. Raise min_score when you want the quick check to reject borderline pages.

#![allow(unused)]
fn main() {
use lectito::ReadableOptions;

let options = ReadableOptions {
    min_content_length: 140,
    min_score: 20.0,
};
}
