Struct ChaserConfig 

pub struct ChaserConfig {
    pub context_limit: usize,
    pub timeout_ms: u64,
    pub profile: Profile,
    pub lazy_init: bool,
    pub chrome_path: Option<PathBuf>,
    pub headless: bool,
    pub viewport_width: u32,
    pub viewport_height: u32,
    pub extra_args: Vec<String>,
}

Configuration for ChaserCF

Fields

context_limit: usize

Maximum concurrent browser contexts (default: 20)

timeout_ms: u64

Request timeout in milliseconds (default: 60000)

profile: Profile

Stealth profile to use (default: Windows)

lazy_init: bool

Whether to defer browser initialization until first use (default: false)

chrome_path: Option<PathBuf>

Path to Chrome/Chromium binary (default: auto-detect)

headless: bool

Whether to run in headless mode (default: false for stealth)

viewport_width: u32

Browser viewport width (default: 1920)

viewport_height: u32

Browser viewport height (default: 1080)

extra_args: Vec<String>

Extra command-line flags to pass to the Chrome process, appended to chaser-cf’s defaults (--disable-blink-features=Automation- Controlled, --disable-infobars).

Common values:

• --no-sandbox — required when the host process runs as root (e.g. systemd unit, Docker containers without --user), otherwise Chrome refuses to start with the message “Running as root without –no-sandbox is not supported”.
• --disable-gpu — for headless servers without a GPU.
• --disable-dev-shm-usage — for /dev/shm-constrained containers.

Default: empty (chaser-cf only sets its own minimum baseline flags).

Implementations

impl ChaserConfig

pub fn from_env() -> Self

Create configuration from environment variables

Environment variables:

• CHASER_CONTEXT_LIMIT: Max concurrent contexts (default: 20)
• CHASER_TIMEOUT: Timeout in ms (default: 60000)
• CHASER_PROFILE: Profile name (windows/linux/macos)
• CHASER_LAZY_INIT: Enable lazy init (true/false)
• CHROME_BIN: Path to Chrome binary
• CHASER_HEADLESS: Run headless (true/false)
• CHASER_EXTRA_ARGS: Whitespace-separated Chrome flags appended to chaser-cf’s defaults (e.g. --no-sandbox --disable-gpu)

pub fn with_context_limit(self, limit: usize) -> Self

Builder method: set context limit

pub fn with_timeout_ms(self, timeout: u64) -> Self

Builder method: set timeout

pub fn with_timeout(self, timeout: Duration) -> Self

Builder method: set timeout from Duration

pub fn with_profile(self, profile: Profile) -> Self

Builder method: set profile

pub fn with_lazy_init(self, lazy: bool) -> Self

Builder method: enable lazy initialization

pub fn with_chrome_path(self, path: impl Into<PathBuf>) -> Self

Builder method: set Chrome path

pub fn with_headless(self, headless: bool) -> Self

Builder method: set headless mode

pub fn with_viewport(self, width: u32, height: u32) -> Self

Builder method: set viewport size

pub fn with_extra_args<I, S>(self, args: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Builder method: replace the extra Chrome args set with the given list. Use Self::add_extra_arg to append a single flag instead.

pub fn add_extra_arg(self, arg: impl Into<String>) -> Self

Builder method: append a single Chrome flag to the existing extras. Useful for chaining, e.g. ChaserConfig::default().add_extra_arg("--no-sandbox").

pub fn timeout(&self) -> Duration

Get timeout as Duration
