Why a probe was inconclusive.

Uncertain outcomes carry a typed reason rather than a free-form string, so logic that reacts to specific cases (e.g. retry on a transient ban) matches an enum variant instead of a fragile string. The fmt::Display rendering is what the CLI prints; serialization is the externally-tagged default (unit variants → a snake_case string, detail-carrying variants → { "network": "…" }).

Variants

RateLimited

HTTP 429, or 503 with a Retry-After header.

CloudflareChallenge

A Cloudflare interstitial / “checking your browser” page.

Captcha

A captcha gate.

RobotsDisallowed

The path is disallowed by the host’s robots.txt (--respect-robots).

Deadline

The scan deadline elapsed before this site finished.

SchedulerClosed

The executor’s scheduler was closed (does not happen in practice).

Network(String)

A transport/network error while issuing the request.

BodyRead(String)

An error reading the response body.

BrowserBudget

A bot-protected site needed the browser backend but the per-scan --browser-budget cap was already spent on earlier sites.

UsernameNotAllowed

The username doesn’t satisfy the site’s regex_check (e.g. too short, contains forbidden characters). Reported without issuing any HTTP request — saves both network and the false-positive class where the site 404s on illegal usernames in ways our signal can’t tell apart from a missing account.

BrowserFailed(String)

The browser backend itself failed (timeout, navigation error, session drop, …) for a bot-protected site.

Other(String)

Any other reason (e.g. a doctor pre-flight skip).

Trait Implementations

impl Clone for UncertainReason

fn clone(&self) -> UncertainReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UncertainReason

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UncertainReason

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for UncertainReason

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

Formats the value using the given formatter.

impl PartialEq for UncertainReason

fn eq(&self, other: &UncertainReason) -> 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 UncertainReason

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
