}

Top-level configuration for a browser session.

Example

use stygian_browser::BrowserConfig;

let config = BrowserConfig::builder()
    .headless(true)
    .window_size(1920, 1080)
    .build();

assert!(config.headless);

Fields

chrome_path: Option<PathBuf>

Path to the Chrome/Chromium executable.

Env: STYGIAN_CHROME_PATH

args: Vec<String>

Extra Chrome launch arguments appended after the defaults.

headless: bool

Run in headless mode (no visible window).

Env: STYGIAN_HEADLESS (true/false, default: true)

user_data_dir: Option<PathBuf>

Persistent user profile directory. None = temporary profile.

window_size: Option<(u32, u32)>

Browser window size in pixels (width, height).

devtools: bool

Attach DevTools on launch (useful for debugging, disable in production).

proxy: Option<String>

HTTP/SOCKS proxy URL, e.g. http://user:pass@host:port.

proxy_bypass_list: Option<String>

Comma-separated list of hosts that bypass the proxy.

Env: STYGIAN_PROXY_BYPASS (e.g. "<local>,localhost,127.0.0.1")

webrtc: WebRtcConfig

WebRTC IP-leak prevention and geolocation consistency settings.

Only active when the stealth feature is enabled.

stealth_level: StealthLevel

Anti-detection intensity level.

cdp_fix_mode: CdpFixMode

CDP Runtime.enable leak-mitigation mode.

Env: STYGIAN_CDP_FIX_MODE (add_binding/isolated_world/enable_disable/none)

source_url: Option<String>

Source URL injected into Function.prototype.toString patches, or None to use the default ("app.js").

Set to "0" (as a string) to disable sourceURL patching entirely.

Env: STYGIAN_SOURCE_URL

pool: PoolConfig

Browser pool settings.

launch_timeout: Duration

Browser launch timeout.

Env: STYGIAN_LAUNCH_TIMEOUT_SECS (default: 10)

cdp_timeout: Duration

Per-operation CDP timeout.

Env: STYGIAN_CDP_TIMEOUT_SECS (default: 30)

Implementations

impl BrowserConfig

pub fn builder() -> BrowserConfigBuilder

Create a configuration builder with defaults pre-populated.

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

Collect the effective Chrome launch arguments.

Returns the anti-detection baseline args merged with any user-supplied extras from BrowserConfig::args.

pub fn validate(&self) -> Result<(), Vec<String>>

Validate the configuration, returning a list of human-readable errors.

Returns Ok(()) when valid, or Err(errors) with a non-empty list.

Example

use stygian_browser::BrowserConfig;
use stygian_browser::config::PoolConfig;
use std::time::Duration;

let mut cfg = BrowserConfig::default();
cfg.pool.min_size = 0;
cfg.pool.max_size = 0; // invalid: max must be >= 1
let errors = cfg.validate().unwrap_err();
assert!(!errors.is_empty());

pub fn to_json(&self) -> Result<String, Error>

Serialize this configuration to a JSON string.

Errors

Returns a serde_json::Error if serialization fails (very rare).

Example

use stygian_browser::BrowserConfig;
let cfg = BrowserConfig::default();
let json = cfg.to_json().unwrap();
assert!(json.contains("headless"));

pub fn from_json_str(s: &str) -> Result<Self, Error>

Deserialize a BrowserConfig from a JSON string.

Environment variable overrides will NOT be re-applied — the JSON values are used verbatim. Chain with builder methods to override individual fields after loading.

Errors

Returns a serde_json::Error if the input is invalid JSON or has missing required fields.

Example

use stygian_browser::BrowserConfig;
let cfg = BrowserConfig::default();
let json = cfg.to_json().unwrap();
let back = BrowserConfig::from_json_str(&json).unwrap();
assert_eq!(back.headless, cfg.headless);

pub fn from_json_file(path: impl AsRef<Path>) -> Result<Self>

Load a BrowserConfig from a JSON file on disk.

Errors

Returns a crate::error::BrowserError::ConfigError wrapping any I/O or parse error.

Example

use stygian_browser::BrowserConfig;
let cfg = BrowserConfig::from_json_file("/etc/stygian/config.json").unwrap();

Trait Implementations

impl Clone for BrowserConfig

fn clone(&self) -> BrowserConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BrowserConfig

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

impl Default for BrowserConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BrowserConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for BrowserConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
