Stable identifier for a built-in stealth detection check.

Variants

WebDriverFlag

navigator.webdriver must be undefined or false.

ChromeObject

window.chrome.runtime must be present (absent in headless by default).

PluginCount

navigator.plugins must have at least one entry.

LanguagesPresent

navigator.languages must be non-empty.

CanvasConsistency

Canvas toDataURL() must return non-trivial image data.

WebGlVendor

WebGL vendor/renderer must not contain the SwiftShader software-renderer marker.

AutomationGlobals

No automation-specific globals (__puppeteer__, __playwright, etc.) must be present.

OuterWindowSize

window.outerWidth and window.outerHeight must be non-zero.

HeadlessUserAgent

navigator.userAgent must not contain the "HeadlessChrome" substring.

NotificationPermission

Notification.permission must not be pre-granted (automation artefact).

MatchMediaPresent

window.matchMedia must be a function (PX env-bitmask bit 0).

ElementFromPointPresent

document.elementFromPoint must be a function (PX env-bitmask bit 1).

RequestAnimationFramePresent

window.requestAnimationFrame must be a function (PX env-bitmask bit 2).

GetComputedStylePresent

window.getComputedStyle must be a function (PX env-bitmask bit 3).

CssSupportsPresent

CSS.supports must exist and be callable (PX env-bitmask bit 4).

SendBeaconPresent

navigator.sendBeacon must be a function (PX env-bitmask bit 5).

ExecCommandPresent

document.execCommand must be a function (PX env-bitmask bit 6).

NodeJsAbsent

process.versions.node must be absent — not a Node.js environment (PX env-bitmask bit 7).

WebDriverDescriptorShape

Navigator.prototype.webdriver should look like a native accessor descriptor.

UserAgentDataPresent

navigator.userAgentData should exist and expose coherent client hints.

ConnectionPresent

navigator.connection should expose plausible network information.

HiddenFontProbeRect

Hidden font-probe elements should yield non-zero layout measurements.

ScreenMetricsCoherent

screen metrics and devicePixelRatio should be plausible and coherent.

AudioContextPresent

The Web Audio surface should exist and expose a non-zero sample rate.

Trait Implementations

impl Clone for CheckId

fn clone(&self) -> CheckId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CheckId

impl Debug for CheckId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CheckId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CheckId

impl Hash for CheckId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CheckId

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
