}

A specific anti-bot mechanism a site is known to deploy. Used to route probes to the right backend (raw HTTP, cloudscraper, full browser) and to inform users what blocks reliable detection.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Cloudflare

Standard Cloudflare WAF — challenge pages, cf_clearance cookie. Bypassable by cloudscraper-style HTTP-level solvers (e.g. FlareSolverr) without a full browser.

Cloudfront

AWS CloudFront edge protection. Often UA-strictness only.

DdosGuard

DDoS-Guard (used by some Russian/CIS hosts). Similar challenge model to Cloudflare.

CfJsChallenge

Cloudflare’s JS-challenge (“I am under attack” mode). Needs a JS-executing backend.

CfFirewall

Cloudflare’s WAF firewall blocking by signature, requiring a real browser fingerprint to clear.

TlsFingerprint

JA3/JA4 TLS-fingerprint matching (servers that classify the client by its TLS handshake shape, not its UA).

Anubis

Anubis proof-of-work challenge. Used by codeberg + a growing number of FOSS projects to discourage scraping.

Captcha

Generic captcha challenge (hCaptcha, reCAPTCHA, …). Almost always blocking — Uncertain is the honest answer.

UserAgent

Trivial UA-strictness: rejects unknown User-Agent strings but lets through a real-browser UA. Cheapest to bypass.

UserAuth

Endpoint requires authentication; no anonymous probe path exists. Practically unscrapable for OSINT.

Trait Implementations

impl Clone for ProtectionKind

fn clone(&self) -> ProtectionKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProtectionKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProtectionKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ProtectionKind

fn eq(&self, other: &ProtectionKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ProtectionKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
