Struct IdentitySurface 

pub struct IdentitySurface {
    pub user_agent: Option<String>,
    pub platform: Option<String>,
    pub languages: Option<String>,
    pub hardware_concurrency: Option<u32>,
    pub device_memory: Option<u32>,
    pub timezone: Option<String>,
    pub screen_width: Option<u32>,
    pub screen_height: Option<u32>,
    pub color_depth: Option<u32>,
    pub webdriver: Option<bool>,
}

Identity surface probed in a single browser context.

All fields are optional so partial probe results (e.g. a context where navigator.deviceMemory is undefined) round-trip cleanly.

Example

use stygian_browser::coherence::IdentitySurface;

let s = IdentitySurface {
    user_agent: Some("Mozilla/5.0 ...".to_string()),
    platform: Some("MacIntel".to_string()),
    languages: Some("en-US,en".to_string()),
    hardware_concurrency: Some(8),
    device_memory: None,
    timezone: Some("America/Los_Angeles".to_string()),
    screen_width: Some(1920),
    screen_height: Some(1080),
    color_depth: Some(24),
    webdriver: Some(false),
};
assert_eq!(s.user_agent.as_deref(), Some("Mozilla/5.0 ..."));

Fields

user_agent: Option<String>

navigator.userAgent.

platform: Option<String>

navigator.platform.

languages: Option<String>

navigator.languages joined by "," for stable comparisons.

hardware_concurrency: Option<u32>

navigator.hardwareConcurrency (allowed to drift for workers).

device_memory: Option<u32>

navigator.deviceMemory (often undefined in workers).

timezone: Option<String>

Intl.DateTimeFormat().resolvedOptions().timeZone.

screen_width: Option<u32>

screen.width (Document + same-origin iframe only).

screen_height: Option<u32>

screen.height (Document + same-origin iframe only).

color_depth: Option<u32>

screen.colorDepth (Document + same-origin iframe only).

webdriver: Option<bool>

navigator.webdriver (Some(false) on a clean browser).

Implementations

impl IdentitySurface

pub const fn is_empty(&self) -> bool

true when no field is populated — useful for asserting a context was probed but produced no observations.

pub fn signature_parts(&self) -> Vec<String>

Build a deterministic signature for crate::freshness::signature_hash.

Concatenates the fields most likely to be anti-bot detection targets: user_agent, platform, languages, timezone, screen_width, screen_height, color_depth. Missing fields emit "-" so signatures are stable across partial observations.

Trait Implementations

impl Clone for IdentitySurface

fn clone(&self) -> IdentitySurface

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IdentitySurface

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

Formats the value using the given formatter.

impl Default for IdentitySurface

fn default() -> IdentitySurface

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for IdentitySurface

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for IdentitySurface

impl PartialEq for IdentitySurface

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
